Description

They are suitable for short circuit and overload protection in circuit of AC690V 50/60Hz, rated current from 12.5A to 630A. Its rated operating voltage is 690V. It can make and break the unfrequent circuit under normal conditions. It takes protective effect when squirell-cage motors
unfrequently start, making&breaking and protecting against overload, short circuit and lacking voltage.

Parameters

Application

1) Moulded Case Circuit Breakers Frequency AC 50Hz /60Hz, rated voltage up to 690V,   rated working current up to 630A.

2)  Used for infrequently switch and starting of motor and for motor overload, short circuit and under-voltage  protections.

3)  Small volume, high breaking capacity, short over-arcing (some of specification is zeroarcing), strong anti-vibration

4)  In accordance with the ultimate short circuit breaking capacity classified into four types: Type C (basic),Type L (standard),

      Type M (middle), Type H (high).
