Schneider type Vigi compact NS series MCCB(moulded case earth leakage circuit breaker, residual current circuit breaker) is a new developed type adopting international advanced design and manufacturing technology it's rated insulating voltage is 690V, AC50/60Hz, rated operating voltage is 230V or 400V, rated operating current under 630A, it is used for unfrequent switching in the circuit. The breaker has overload sort circuit and under voltage protectiong device, which can prevent the circuit and power equipment form damage, meanwhile the breaker can supply human body with indirect contact and fireproofing protection, and also supply protect to long existing grounding fault which can not be checked out by overcurrent protection.
The breaker can be sorted as N type(middle high breaker) and H type(high breaking) according to rated limited.
Short circuit breaking capacity it has characters of small volume, high breaking capacity, short arc, aseismatic, optional earth leakage operating value/time.

NSX Moulded Case Circuit Breaker is the one of the most advanced type NS series of Circuit Breakers in the world, which adopts international advanced design and manufacture technology. They are suitable for short circuit and overload protection for circuit of AC 690V 50/60Hz, rated current from 12.5A to 1600A. It takes protecting effect when motors non-frequent start, breaking off working and protecting overload, short circuit and lacking voltage. Fixed or withdrawable, front or rear connection, manual operating mechanism or motor mechanism is choice.
