Product summary

YEM1 series moulded case circuit breaker(hereinafter referred to circuit breaker) is applied in the circuit of AC 50/60HZ,its rated isolation voltage is 800V,rated working voltage is 400V,its rated working current reaches to 800A. It is used to transfer infrequently and infrequent motor start(lnm≤400A). Circuit breaker with over-load, short circuit and under-voltage protection function so that protects the circuit and power supply device from being damaged. This circuit breaker has the features of small volume,high breaking capacity,short arc and anti-vibration.

Circuit breaker can be installed in a vertical way.

Circuit breaker has isolation function.
