NBT2-125DC series high-voltage DC miniature circuit breakers are mainly used in photovoltaic, energy storage and other DC systems that need breaking and protection. The maximum rated voltage is 1000VDC, and the rated current is 125A. With scientific arc extinguishing and current limiting mechanisms, they can quickly disconnect the fault current on the DC side to ensure the reliable operation of the DC system.
Product classification
The topological principles of DC circuit breakers are complex and diverse. According to the different key breaking devices in DC circuit breakers, DC circuit breakers can be divided into three categories: mechanical DC circuit breakers, all solid state DC circuit breakers, and hybrid DC circuit breakers that combine mechanical switches with solid state switches.
Working conditions
1.In the place where there is no explosive medium in the air and there is no gas and conductive dust that can corrode metal and damage insulation.
2.A place free from rain and snow.
3.The pollution level is 3.
4.Installation category: the installation category of the main circuit of the circuit breaker is III, and the installation category of the auxiliary circuit and control circuit not connected to the main circuit is II
