Anonymous users2024-02-06The M series low-voltage circuit breaker is an imitation of Schneider.
The products have plastic shell and frame type, and the frame type has a large breaking capacity; The DZ15 series is a molded case switch with a maximum rated current.
Not more than 100a; It has a much larger breaking capacity than the DZ47 (micro-break); DZ20 series molded case switch, the maximum rated current may be up to 800A, right? The breaking capacity is much greater than that of the DZ15. The breaking capacity of DZ47 micro-breaking does not exceed 6KA, and the maximum rated current is less than 63A.

Anonymous users2024-01-30All three models are miniature circuit breakers
There are three main types of DZ47: DZ47-60 miniature circuit breaker, DZ47LE-32 residual current action circuit breaker, and DZ47LE-63 residual current action circuit breaker.
1) DZ47-60 miniature circuit breaker (type C) is suitable for the power distribution system (type D) of lighting distribution system or motor, mainly used for AC 50Hz 60Hz, single letter positive rip level 230V, two, three, four and 400V, current to 60A in the line circuit to play overload and short circuit protection, but also can be used under normal conditions to open and off electrical devices and lighting circuits infrequently.
2) DZ47LE-32 residual current action circuit breaker is suitable for AC 50Hz 60Hz, rated voltage 400V, rated current to 32A circuit, for residual current protection. When a person is electrocuted or the leakage current of the circuit exceeds the specified level, the residual current action circuit breaker can cut off the power supply in a very short time, protect personal safety and prevent accidents caused by leakage current.
3) DZ47LE-63 residual current action circuit breaker is suitable for AC 50Hz 60Hz, rated voltage 400V, rated current to 60A circuit, the function is the same as DZ47LE-32.
The DZ267 is only available in two models: the DZ267-32 miniature circuit breaker and the DZ267L-32 leakage circuit breaker, which are mainly used for AC 50Hz 60Hz, rated voltage 230V, rated current up to 32A, especially suitable for industrial and commercial lighting.
There are two types of DZ158-100 miniature circuit breaker and DZ1587LE-100 circuit breaker residual current action pier circuit breaker, which is mainly used for AC 50Hz 60Hz, single-stage 230V, second, third, quad and 400V, current 60A to 100A

Anonymous users2024-01-27The main difference between the circuit breaker DZ47-60C10 and the DZ47-60D10 is that the trip curve is different, the circuit breaker.
The tripping curve reflects the functional relationship between the tripping time of the circuit breaker and the expected current under the specified operating conditions, and is generally divided into the following categories according to the load protected by the circuit breaker
Type A: The detaching action current of the tripper is 2-3 times the rated current, which is suitable for protecting semiconductors and electronic circuits;
Type B: The detaching action current of the tripper is 3-5 times the rated current;
Type C: The detaching action current of the tripper is 5-10 times the rated current; It is suitable for the protection of conventional loads and distribution lines, such as the well-known lighting lines. C-curved circuit breakers are often used for protection.
Type D: The detaching action current of the tripper is 10-14 times the rated current; It is suitable for the protection of power lines, such as the load is an electric motor, etc.
These curve pairs have inverse time characteristics, and we generally choose them according to the load situation and nature when using.
Hope it helps.

Anonymous users2024-01-25The cave is close at hand in the world. The number of rafters can be cast everywhere.
The "high-voltage vacuum circuit breaker" is named because the arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are both high vacuum; It has the advantages of small size, light weight, suitable for frequent operation, and no need for maintenance for arc extinguishing, and is widely used in the distribution network. A Brief History In 1893, Rittenhouse in the United States proposed a vacuum interrupter with a simple structure and obtained a design patent. In 1920, the Swedish company Phogat made the first vacuum switch. >>>More
In our lives, we will use a lot of large electrical appliances, so if we don't pay attention to it, there may be a hidden danger of electric shock, in order to protect our safety, the leakage circuit breaker was invented. So what is a leakage circuit breaker? How to choose a leakage circuit breaker? >>>More
The role of the high-voltage circuit breaker:
The electrical energy can be reasonably distributed, and the electric equipment can be started to protect the current. However, when the current load is too large or a short circuit occurs, the current is automatically cut off to reduce the fault range. In addition, after the fault current is cut off, there is no need to replace the parts, which is more convenient to use. >>>More
The delay protection characteristics of the circuit breaker include four main protection functions: overload long delay protection, short-circuit short-delay protection, short-circuit instantaneous protection and grounding fault protection. Now its protection functions are concentrated on the same controller, through the panel operation for a variety of protection characteristics setting, universal circuit breaker supporting controller models are now divided into: >>>More
