Description
Product Overview
This ComPacT NSX250F is a complete 4P 4D 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 36 kA rms at 415 V AC 50/60 Hz. The operational voltage is 690 V AC 50/60 Hz. This product embeds a 250 A rating thermal-magnetic trip unit (TMD). TMD trip unit provides an adjustable thermal overload protection and a fixed magnetic protection. This 4 poles version (14 cm x 16.1 cm x 8.6 cm) comes with a variety of optional functions and accessories. It is compliant with international standards IEC 60947, CCC, EAC and marine specifications. ComPacT NSX250F is part of Schneider Electric EcoStruxure Power architecture.
