circuit breaker Compact NS1250N - Micrologic 2.0 - 1250 A - 3 poles 3t

This Compact NS1250N 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 1250A rating. Micrologic 2.0 trip unit provides adjustable long time and instantaneous protections. This 3 poles version (327mm x 210mm x 147mm) 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 NS1250N is part of Schneider Electric EcoStruxure Power architecture.
