How to choose a household residual current circuit breaker? What brand is good quality?

First of all, clarify the size of your own electricity load, the electricity consumption of your own large appliances and small appliances, in addition to the fixed electricity consumption here, but also have a set aside electricity quota.

The function of household leakage circuit breaker is to ensure the safety of the design of electrical equipment, so safety must be the priority. Therefore, it is very important to choose a household leakage circuit breaker, and the quality and reliability of the product must be the priority.

There are many kinds of brands, divided into domestic and international brands, generally speaking, international brands are more than 2 times more expensive than domestic brands, domestic brands are Zhengtai, Delixi, international brands are Siemens, Schneider, etc. Although it is slightly more expensive, it is still recommended to use an international brand of leakage circuit breaker. It is sold at a building materials store of a slight size.

When leaking electrical appliances, it is recommended to buy multiple small leakage shorts, and use leakage circuit breakers separately in kitchens, bathrooms, and rooms. Household leakage appliances are generally 32 40A (A) is sufficient, and when you buy it, it is best to bring an RCBO (with short circuit and overload protection).

The leakage switch in the house is not long ago, very old. Recently, the old tripped, it seems to be replaced, what are the good suggestions for everyone, to detect where is the leakage problem: first you said that the size of the line and the leakage switch are not the same thing, no matter how big the line at your home is, it should be how much power, this has nothing to do with leakage, the leakage switch is to protect people from the problem of electric shock, and the load has nothing to do, that is, it has nothing to do with the size of the fuse, you can buy a set of switches, that is, the combination of the air switch and the leakage switch together, the leakage protection will be disconnected from the circuit, after troubleshooting and the turn on itIn the same way, overload, short circuit, and overcurrent will also trip, disconnect the circuit, and after troubleshooting and turn on, you don't need to change the fuse, but it is recommended that you find an electrician to help you replace it, and don't connect the wrong line, which will bring unnecessary trouble.

There are not too many requirements for the selection of leakage switches and air switches, choose a first-class point, the regular manufacturer can produce it, but the air switch is best selected according to the load in your home, generally a little larger than the maximum electricity load in your home, and not too large. It is recommended to find a professional master to help you replace it, so that it is more assured to operate.

The circuit breaker is selected according to the power of the consumer.

Calculate the total power of the home first, and then select the leakage switch according to the power.

With power, voltage is equal to current. For example, if the total power of electrical appliances is 4kw, then 4000 220 = 18a.

It is required that the rated current of the leakage switch should be greater than the load current, and in general, the choice of the total leakage switch is according to the load current.

In general, a high-sensitivity leakage protector with a leakage current of 30 mA should be selected for household leakage protection.

Low-sensitivity leakage protectors with a leakage current value of 50 mA or more cannot be used as household leakage protection. However, if you choose a lower leakage current value, it may malfunction and affect normal use.

Of course, the circuit breaker is CHINT circuit breaker, ***, mainly with good safety performance, and there is a small circuit breaker for home use at home, and I use CHINT at home.

CHINT's circuit breaker is good, ** is also very suitable, we use CHINT's circuit breaker here, when the north is very cold, it is minus ten or twenty degrees, and it does not affect the performance, which is very reassuring.

Schneider Electric is recommended for circuit breakers, and big brands are more secure to use. In particular, it is recommended that their RESI9 circuit breaker, the design materials and workmanship are very good in all aspects, and when encountering electrical safety problems, it can be broken when it is broken, short circuit caused by high load electricity**, leakage, electric shock, and various electrical hazards are no longer afraid, in addition, I have to say that the appearance of RESI9 circuit breaker is also quite high, to a certain extent, you can increase a sense of happiness, and you can learn about it if you are interested.

Leakage switch has become an indispensable product in home improvement, because leakage switch can prevent leakage when electrical appliances fail, thereby causing harm to the human body, but many people do not know which brand to choose when buying leakage switch, so which brand of leakage switch is good? How to choose a household leakage switch? Let's take a look!

First, which brand of leakage switch is good There are many leakage switch brands on the market, mainly divided into international brands and domestic brands, better domestic leakage switch brands are Delixi and Zhengtai, as for international brands, the relatively well-known leakage switch brands are Schneider, Siemens, etc., whether it is to buy international brands or domestic brands of leakage switches, it is recommended that you find brand stores to buy. 2. How to choose a household leakage switch 1. At present, the quality of the best household leakage switch on the market is uneven, so in the process of purchasing a leakage switch, you should pay attention to check whether the product has passed the national quality inspection, you can see whether there is a certification word in the product manual, if you can't see the certification word in the manual, you must not buy. 2. When choosing a household leakage switch, it is necessary to see whether the performance warranty of the leakage switch is consistent with the needs of household electricity, such as the number of stages of the leakage switch, rated voltage, etc., as for the leakage protector, it is divided into three kinds according to the grade, and the household leakage switch can be selected as level 2.

2. In the process of purchasing a leakage switch, you can not ignore the rated leakage action current of the leakage switch, and pay attention to check the sensitivity of the leakage switch, it is recommended that you buy a leakage switch with a sensitivity of less than 30mA, this kind of leakage switch has high sensitivity and is safer to use. Summary: The relevant content of which brand of leakage switch is good is introduced to you here, and I hope to help friends in need.

There are many electrical appliances that need to be used in home life, so it is recommended that you install a leakage switch at home to ensure the safety of household electricity.

Do the math how much it will cost you to renovate your home

The improvement of living standards has made more and more household appliances enter our lives. There are safety problems in electrical appliances, which means that electricity safety has become more important. Household leakage circuit breakers have gradually entered our lives, and household leakage circuit breakers are designed to protect our safe electricity.

After installing it, we can use electricity with more confidence. Nowadays, there are many types of household leakage circuit breakers. The following is an introduction to the purchase skills of household leakage circuit breakers.

Household leakage circuit breaker purchase tips

1. In line with the national technical standards At present, the leakage protector sold on the market can be described as a mixture, the product is not the same, we must pay attention to whether the product has passed the national standard GB6829-86 "leakage current action protector", this parameter can be found in the manufacturer's product manual, the general format is: "through the China Electrical Products Certification Committee safety certification, certificate number: **in line with the standard:

BG6829-86 "If you can't find this word on the manual, you must not buy it."

2. The selected product technical performance indicators are suitable for the electricity needs of family life.

Rated voltage, frequency, number of stages.

The rated voltage of the leakage protector is only 220V and 380V, and the household electricity belongs to the single phase of electricity, so the voltage is AC 220V 50Hz. There are three levels of leakage protectors, and general home use can choose 2 levels.

3. Rated current and rated current of overcurrent tripper The rated current specifications of the mainstream leakage protector are more, but the rated current of the overcurrent tripper is only 10A, 16A, 20A, and it should be noted when purchasing that the alternating current is 220V working voltage, and the user can rudely calculate the rated current of the leakage protector according to the current of 1KW load 5A. In general, the rated current value of the overcurrent tripper can be determined according to the rated current value of the times.

4. Rated leakage current.

The rated leakage current refers to the leakage current value that ensures that the leakage protector is not allowed to operate, which is divided into three levels.

When we choose a household leakage circuit breaker, the first thing we should pay attention to is that the leakage circuit breaker we choose must meet the national standards. Products that meet national standards are more secure. This is also the most important issue we need to pay attention to when buying, and other matters that need to be paid attention to have been introduced in detail in this article, which you can use as a reference.

What I want to say here is that now the types of household appliances are gradually increasing, and leakage circuit breakers can give us a better protection. You can consider buying one.

Yes. With the increasing popularity of household appliances (increasing), the load current of many households has far exceeded the rated current of the leakage protector on the line originally designed and installed, causing the leakage protector to trip. This situation generally occurs in the use of high-power household appliances such as air conditioners and electric kettles, and the problem can be solved as long as a matching leakage protector is replaced.

Load or line leakage, short circuit: If it is a leakage or short circuit of a load such as a household appliance and the leakage protector trips, as long as Suichai unplugs the faulty household appliance plug, it can be re-transmitted.

Very good,The circuit breaker has beautiful appearance, small size, light weight, high breaking capacity, fast tripping, guide rail installation, high flame retardant and impact-resistant plastic for housing and components, excellent and reliable performance.

There are many kinds of leakage circuit breakers, and we need to choose them according to the purpose of use and operating conditions. According to the purpose of use, generally speaking, in order to prevent people from being electrocuted, we can choose a high-sensitivity and fast leakage circuit breaker.

However, if it is a branch line that is used to ground the equipment for the purpose of preventing electric shock, you can choose a medium-sensitivity, fast leakage circuit breaker. If it is a trunk line for the purpose of preventing fire caused by leakage and protecting lines and equipment, a medium-sensitivity, time-delay leakage circuit breaker should be selected.
