Product detail

Product summary

YEM1L series moulded case earth leakage circuit breaker(hereinafter referred to leakage circuit breaker) is applied in the circuit of AC 50/60HZ,its rated insulation voltage to 800V,rated working voltage to 400 V,rated current reaches to 630A.It is used to transfer infrequently and protect motor. Circuit breaker has over-load,short circuit and under-voltage protection function so that protects the circuit and power supply device from being damaged. At the same time,it can provide indirect contact protection for people, and it can also provide protection for fire rise which may be caused long-term ground faults that cannot be detected by over-current protection. When other protective devices fail, the leakage current circuit breaker YEM1L with a rated residual current of 30mA can directly act as an additional protection.
1.This circuit breaker can be equipped with leakage alarm and non tripping module to avoid heavy losses caused by power failure.
2.This circuit breaker has the features of small volume,high breaking ability,short arc and anti-vibration.
3.Circuit breaker can be installed in a vertical way.
4.The circuit breaker can not be poured into the line,that is only the 1、3、5 is allowed to connect the power line,and the 2、4、6 is connected to the load line.
5.Circuit breaker has isolation function.

Operating conditions

1.Environment temperature:-5℃~+40℃.
2.Altitude:≤2000m.
3.The relative humidity of the air at the installation site does not exceed 50% at a maximum,for example:relative humidity of 90% at 20℃,special measures should be taken for condensation that occasionally occurs due to temperature changes.
4.Pollution degree 3.
5.The circuit breaker passes the GB/T2423.10 test requirement to withstand frequency of 20HZ~13.2HZ、displacement of ±1mm and frequency of 13.2HZ~100HZ、and an acceleration of ±0.7g.
6.The main circuit installation category of the circuit breaker is Ⅲ,and the remaining auxiliary circuit and control circuit installation category is Ⅱ.
7.The circuit breaker is suitable for electromagnetic environment A.We provide fantastic energy in top quality and advancement,merchandising,gross sales and marketing and operation for IOS Certificate China Professional Manufacturer MCCB 3p ELCB Factory Circuit Breakers, Because we stay with this line about 10 years.
