NM8N-HV

This NM8N High-voltage (HV) Series Molded Case Circuit Breaker is specially designed for higher voltage application, capable to break heavy loaded electrical circuit systems under wide range of operating temperature of - 40 ℃ ~ + 70 ℃ . The characteristics of this Circuit Breaker is its capability to break circuit with zero arcing, which is an ideal component for meeting the requirements of many systems such as the solar (PV) power generation system. This Circuit Breaker works perfectly up to the maximum working voltage of AC 1150V, which can effectively protects electrical systems like the output loading of the string Inverters, and others such as the loading capacity of the AC combiner box in the photovoltaic systems.

Rated Voltage Ue(V)： AC 690/800/1000/1150 ;

Frame Size current: 250, 400, 630;

Rated insulation voltage: 1250V

Rated impulse withstand voltage: 8kV ( frame size: 250A) 12kV ( frame size: 400A, 630A)

Rated ultimate short-circuit breaking current(kA) @AC800v : 36, 50

Rated service breaking current(kA)@AC800v : 36, 50 (Please refer to the catalog for details)

Selectivity category: A

Poles: 3P

Release units type: Thermal magnetic (TM), Magnetic (M)

Ambient temperature: -40℃ ~+70℃

Standard complied: IEC/EN 60947-2
