Product Description
This circuit breaker is part of the new generation of ComPacT NS630bN to NS3200 range. ComPacT NS new generation keeps the same performances and comes with a new transparent front cover for auxiliaries visibility and a new toggle with ergonomic touch and optional LED trip status. It is possible to add as an option the new wireless auxiliary contact OF/SD in ZigBee communication protocol. This ComPacT NS1250N is a complete 3 poles circuit breaker designed to optimize space and breaking capacity. It is a fixed circuit breaker manually operated. 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 control unit, with 1250A rating. MicroLogic 2.0 control unit provides adjustable long time and instantaneous protections (ANSI codes 49/50). This product comes with a variety of optional functions and accessories. The dimensions are 32.7 cm (Height) x 21 cm (Width) x 14.7 cm (Depth). It is compliant with IEC 60947-1 and IEC60947-2 international standards. ComPacT NS new generation is part of Schneider Electric EcoStruxure Power architecture. ComPacT NS new generation is more sustainable with green packaging and green partnerships.
