Moulded Case Circuit Breaker(NS series)
| Model NO.: | NS series |
|---|---|
| Breaking Capacity: | Low Voltage Circuit Breakers |
Product Description
NS series moulded case circuit breaker is one of the most advanced type breaker in the world, which adopts international advanced design and manufacture technology. They are suitable for short circuit and overload protection in circuit of AC 690V 50/60Hz, rated current from 12.5A to 630A. Its rated insulation voltage is 690V. It can make and break the
Unfrequently circuit under normal conditions. It takes protecting effect when mouse cage motors unfrequently start, making& breaking and protecting against overload, short circuit and lacking voltage.
