CHINT HV Module Case Circuit Breaker MCCB NM8N

Description

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.
