Description for Schneider Electric Compact NSX100B circuit breaker TMD 40A 3 poles 3d LV429554
Schneider Electric Compact NSX100B circuit breaker TMD 40A 3 poles 3d LV429554
This Compact NSX100B 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 25kA rms at 415VAC 50/60Hz. The operational voltage is 690VAC 50/60Hz. This product embeds a 40A 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 NSX100B is part of Schneider Electric EcoStruxure Power architecture.
