Product Description

3 pole 4 pole 80A-1600A Telemecanique Electrical EZD Ns NSX MCCB Merlin Gerin MCCB Moulded Case Circuit Breaker

NS(NSX) series Mouled case circuit breaker (following call the breaker) is one new type breaker which this company adopts international advanced design. manufacture technology to develop. The rated insulating voltage is 950V, suitable for AC 50Hz (60Hz), rated working voltage 690V and under it, rated working current is 100A~1250A of circuit. Using in distributing electric energy, frequent closing and breaking in the normal cases and protecting when circuit and installation are overload, short circuit and lacking voltage.
