YIFA Intelligent leakage molded case circuit breaker DZ47LE-100 Series
Inquire NowThe circuit breakers DZ47LE-100 is suitable for the electric circuit which is AC 50Hz, rated operational voltage 400V, rated current from 63A to 100A with the function of the leakage, overload and short-circuit protection and so on.
Product description
Dz47le-100 series intelligent leakage circuit breaker has the function of signal control tripping, which is suitable for the lines with AC 50Hz, rated working voltage of 400V and rated current of 63A to 100A. It can be used for long-distance control and automatic signal control and breaking, and also plays the role of overload and short-circuit protection for the line, and can also be used as the infrequent operation and conversion of the line.
At present, it is widely used in IC card prepayment watt hour meter to control the on-off of the line. At the same time, it can protect the overload or short circuit of circuit and motor, and it can also be used for infrequent switching of circuit and infrequent starting of motor.
The product meets the standard of GB 14048.2 and IEC 60947-2.
