GTB7Z-63 series mini DC circuit breakers are mainly used for overload and short circuit protection of DC electrical circuits and equipment with rated voltage up to and including 1000V and rated current up to 63A. It can also be used in solar photovoltaic power generation system, which can quickly break the fault current of DC power distribution system, and protect PV modules in solar power generation system against reverse current from DC side and AC side feedback current caused by inverter fault. The reliable operation of solar power systems.

Standard: GB/T14048.2-2012（IEC60947-2）
