The circuit breaker has a long tome delay against overload. Short circuit short time time delay time limit,short circuit short time delay fixed time limit,short circuit instantaneous protection function,it also can protect the circuit and power supply equipment from damage.
YEM1E series moulded case electronic circuit breaker(hereinafter referred to circuit breaker) is applied in the circuit of AC 50HZ/60HZ,its rated insulation voltage to 800V. It work in rate working voltage is 690 V or below, and the rate working current is 800A. It is used to transfer infrequent motor start. The circuit breaker has a long tome delay against overload. Short circuit short time time delay time limit,short circuit short time delay fixed time limit,short circuit instantaneous protection function,it also can protect the circuit and power supply equipment from damage.
