Information
This ComPacT NSX250 is a complete 4P 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 50kA rms at 1500DC. The operational voltage is 1500VDC. This product embeds a 320A rating thermal-magnetic trip unit (TMD). TMD trip unit provides an adjustable thermal overload protection and a fixed magnetic protection.
