Scope of Application

TXGV2 Molded Case Circuit Breaker (also known as motor protection circuit breaker, MPCB Circuit Breaker), is the new circuit breakers using international advanced design and manufacturing technology to research and develop. TXGV2 motor protection circuit breaker (MPCB Circuit Breaker) has a small size, high breaking current, short arc, anti-vibration. The rated insulation voltage is 750V, applies for the circuit of AC 50Hz, rated current of 0.1A-80A, for protecting overload, open phase, short-circuit and infrequent start of three-phase squirrel cage induction motor. TXGV2 motor protection circuit breaker (MPCB Circuit Breaker) can be used for distribution circuit protection and infrequent load conversion, also for isolation.
TXGV2 motor protection circuit breakers (MPCB Circuit Breaker) meet the standards: IEC60947.2, GB14048.2, GB14048.4.
