Information
ComPacT NSX 250F DC is a complete 4 poles fixed circuit breaker designed to optimize space and breaking capacity. It's an optimal choice for applications using DC voltages. The breaking capacity (Icu) is 10kA rms at 1000VDC. The operational voltage is 1000VDC. This product embeds a 250A rating thermal-magnetic trip unit (TM-DC). TM-DC trip unit provides an adjustable thermal overload protection and an adjustable magnetic protection. The dimension is 255mm x 185mm x 110mm (H x W x D). It is compliant with international standard EN/IEC 60947.
