JVM2X series plastic case circuit breaker is one of the new circuit breakers developed by our company using international advanced technology. Its rated insulation voltage is 750V, suitable for AC 50Hz or 60Hz, rated working voltage of 690V and below, and rated working current of 12.5A to 630A. It is used to distribute electric energy, and it is not frequently closed and disconnected under normal conditions. It is used as a protection when the circuit and equipment are overloaded and under-voltage. Circuit breakers with rated frame currents of 400A and below can also be used for infrequent starting of squirrel-cage motors, disconnection during operation, and protection when the motor is overloaded, short-circuited, and under-voltage. The product complies with the IEC60947-2 standard.
