GYCM3E series electronic circuit breakers(hereafter simply referred to as circuit breakers) are one of the new type breakers which have been developed using international advanced design and manufacturing technology. The rated insulation voltage of the breakers is 800V. In the circuit of AC50Hz, the rated working voltage 690V or bellow and the rated working current up to 800A, the breakers are suitable for infrequent turn-on or turn-off and infrequent motor starting-up. The breakers have overload long-time-delay inverse, short-circuit short-time delay, short-circuit instantaneous and under-voltage protection performances, so as to protect the circuit and the power equipment from damage. Circuit breaker protection features complete and accurate, can improve the reliability of power supply and avoid unnecessary power failures.
