Details
Compact NSX 400S DC is a complete 3 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 100kA rms at 750VDC.
The operational voltage is 750VDC.
This product embeds a 400A rating thermal-magnetic trip unit (TM-DC).
TM-DC trip unit provides an adjustable thermal overload protection and an adjustable magnetic protection.
This 4 poles version (255mm x 140mm x 110mm) comes with a variety of optional functions and accessories.
It is compliant with international standards (IEC 60947), CCC, EAC and marine specifications.
