Description
Anson electric ComPacT NCM2(NSX250F) is a complete 2 poles 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 240VAC 50/60Hz. The operational voltage is 277VAC 50/60Hz. This product embeds a 160A rating thermal-magnetic trip unit (TMD). TMD trip unit provides an fixed thermal overload protection and a fixed magnetic protection. The dimension is (161mm x 70mm x 86mm ). It is compliant with international standards (EN/IEC 60947), CCC, CE and marine specifications. Compact NCM2-250F is part of Anson Electric EcoStruxure Power architecture.
