A nominal insulation voltage is 750V, suitable for AC 50Hz/60Hz, nominal working voltage 690V and below, nominal working current of 12.5A~630A in the current, used to distribute electricity, in normal conditions to do not frequently closure and disconnect use, and in the line and equipment overload, low voltage when protecting around. Rated shell grade current at 400A and below the circuit breaker, can also do mouse cage type electric motor's non-frequent start, operation interruption and play a protective role when the electric motor's overload, short circuit, low voltage.
