circuit breaker Compact NSX250F, 36 kA at 415 VAC, TMD trip unit 250 A, 3 poles 3d
in stock: 5
Description
This Compact NSX250F is a complete 3P 3d 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 36kA rms at 415VAC 50/60Hz. The operational voltage is 690VAC 50/60Hz. This product embeds a 250A rating thermal-magnetic trip unit (TMD). TMD trip unit provides an adjustable thermal overload protection and a fixed magnetic protection. This 3 poles version (105mm x 161mm x 86mm) 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.
