Description:
Anson Electric this Compact NCM2 (NSX350N) is a complete 3 poles fixed circuit breaker designed to optimize space and breaking capacity. It is an optimal choice for all standard and specific applications. The breaking capacity (Icu) is 50kA rms at 415VAC 50/60Hz. The operational voltage is 690VAC 50/60Hz. The circuit breaker can be manually operated with ON, OFF or “push to trip” buttons. This product embeds an electronic Micrologic 2.0 trip unit, with 350A rating. Micrologic 2.0 trip unit provides adjustable long time and instantaneous protections. This 3 poles version (140mm x 255mm x 110mm) comes with a variety of optional functions and accessories. It is compliant with IEC 69947-1 and IEC60947-2 international standards and marine specifications. Compact NCM2-350N is part of Anson Electric EcoStruxure Power architecture.
