Description
BB2-63PT Miniature Circuit Breaker for Metering Circuits (hereinafter referred to as the circuit breaker) is a special low-internal-resistance MCB developed by our company for short-circuit fault protection of the secondary voltage circuit in the electric energy metering system of power supply authorities. While providing effective overcurrent fault protection for the system, it can reduce the impact of the breaker’s internal impedance on metering accuracy. This product complies with IEC60947-2 ,GB/T14048.2.
