ComPacT NSX1200N DC is a complete 2 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 50kA rms at 600VDC. The operational voltage is 600VDC. This product embeds a 630A 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 350mm x 185mm x 110mm (H x W x D). It is compliant with international standards (EN/IEC 60947), CCC, EAC and marine specifications.
