IP54 protection level for electrical cabinets, what is the protection level of IP54

The protection level in industrial applications is generally: IP65, and the highest level is IP68But the degree of protection IP54

If the genus level is low, IP is the marking letter, the number 5 is the first marking number, and 4 is the second marking number, the first marking number indicates the contact protection and foreign object protection level, and the second marking number indicates the waterproof protection level.

Dustproof grade prevents harmful dust build-up.

Waterproof rating. Liquid spilled into the casing from any direction has no harmful effect.

Please note when testing:

You can choose whether there is negative pressure during the test, and the negative pressure is the same as IP6X. Vacuum the inside of the product to generate negative pressure!

Simulate the rain environment, 360 all-round rain shower!

4- Splash-proof type: Affected by water splashing in any direction, no harmful effect.

5- Anti-jet type: Any direction is directly affected by the spray of water, and there is no harmful effect.

Protection and explosion-proof levels.

It has nothing to do with it, it can only be said that most of the occasions that require explosion-proof use a higher protection level such as IP55, but the protection level of IP54 can also be used in explosion-proof occasions.

The IP54 protection level of the electrical cabinet is relatively low, IP5X refers to the fact that it can be dustproof without ventilation and heat dissipation inside and outside the cabinet, but once the device in the cabinet runs and the heat needs to be ventilated and dissipated, the IP5X filter fan can not be dustproof, to put it bluntly, the IP5X filter fan or wind window (also called fan and filter) needs to be ventilated and dissipated when the cabinet body needs ventilation and heat dissipation, it becomes a useless furnishing in terms of dustproof, and if you want to be able to ventilate and dissipate the cabinet body, you need to use IP64 65 filter fan to achieve dustproof when ventilating and dissipating heat. At this time, the cabinet can be IP5X dustproof, because the cabinet does not need ventilation, and the filter fan or windshield that needs to be ventilated.

Electrical cabinet design, IP54 protection level:

The first 5 in IP54 stands for dustproof and completely prevents the intrusion of foreign objects. Although it is not possible to completely prevent dust ingress, the amount of dust that enters does not affect it.

The first 4 in IP54 stands for protection against the intrusion of splashed water, which prevents water from splashing in all directions from entering the shell and causing damage.

The highest protection level is IP68 electrical cabinet, which can be immersed in water under the specified water pressure for a long time, and the general electrical cabinet is IP54 rated.

"IP54", i.e. dust resistance is class 5: It cannot completely prevent dust intrusion, but the amount of dust invading will not affect the normal operation of the product; Waterproof class 4: Prevent the intrusion of splashed waterPrevent the intrusion of water from all directions.

The waterproof rating is 4: Prevent the intrusion of splashed waterPrevent the intrusion of splashing water from all directions. The application of the protection level in industry is generally as follows:

IP65, the highest level is IP68 But the protection level IP54 is a lower level, IP is the marking letter, the number 5 is the first marking number, 4 is the second marking number, the first marking number indicates the contact protection and foreign object protection level, and the second marking number indicates the waterproof protection level.

The standard of the waterproof rating.

1. Air pressure resistancePut the watch in the air with an air pressure 2 105 pa (2 bar) higher than the normal atmospheric pressure, and measure the air leakage rate entering the case (detected with a special instrument). Air leakage rate 50 mcg min.

2. Water pressure resistance immerse the watch in a container containing water, and apply a pressure value equal to the overpressure mark value within 1 minute, if the pressure value of the watch without the overpressure mark is 2 105Pa (2bar), and keep it for 10 minutes, and then, the pressure should be reduced to the surrounding environment pressure within 1 minute. Do the condensation test, and the inner surface of the surface glass shall not appear condensation.

IP55 protection level means that the dust resistance level is 5 and the water resistance level is 5 (the first number is dustproof, and the second value is waterproof).

IP5 dustproof rating, dustproof Meaning: It cannot completely prevent dust from entering, but the amount of dust entering must not affect the normal operation of the equipment and must not affect safety.

0: No protection.

1: Water droplets dripping into the shell have no effect.

2: When the shell is tilted to 15 degrees, water droplets dripping into the shell have no effect.

3 : No effect of water or rain from 60 degrees corner to the enclosure.

4: Liquid splashed into the shell from any direction has no harmful effect.

5: Rinse with water without any harm.

6: Can be used in the environment of the cabin.

7: It can be immersed in water (1m) in a short time.

8: Immersion in water for a long time under a certain pressure.

The meaning is as follows:The first digit "5" in IP55 indicates the dust resistance level factor, which means that it is impossible for the device to completely prevent dust from entering, but the amount of dust entering will not cause harm to the device; The second number "5" in IP55 indicates the waterproof rating factor, which means that water shot at the cabinet from every direction should not cause damage.

Introduction:

The protection class (IP number) of the SPD encapsulation material is tested in accordance with DIN EN 60529 (VDE 0470 Part 1). It is also a level of dust and water resistance, which is usually expressed by (ipxx). The protection class (IP number) of the SPD encapsulation material is tested in accordance with DIN EN 60529 (VDE 0470 Part 1).

ip is the marker letter, the number 5 is the first marker number, and 4 is the second marker numberThe first marking number indicates the level of contact protection and protection against foreign objects, and the second marking number indicates the level of protection against water.

ip54Ingress protectionIt refers to a dust resistance level of 5Waterproof rating. is level 4. The protection level of the enclosure of electrical and electronic products is IP54. That is, the dust proof is level 5, which cannot completely prevent dust intrusion, but the amount of dust intrusion will not affect the normal operation of the product; Waterproof class 4: Prevent the intrusion of splashed waterPrevent the intrusion of water from all directions.
