Vigi compact NS series RCCB(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.
