Information
This ComPacT NSX250HB2 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 100kA rms at 500VAC 50/60Hz and 100kA rms at 690VAC 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 4 poles version (140mm 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 NSX250HB2 is part of Schneider Electric EcoStruxure Power architecture.
