Main Circuit Breaker (MCCB), Contactor, Wire
9-8-1. Molded case circuit breaker (MCCB) or earth leakage circuit breaker (ELCB)
MCCB or ELCB as the power switch of the inverter also plays a protective role to the power
supply. Note: do not use MCCB or ELCB to control start/stop of the inverter. The capacity of the
circuit breaker is 1.5~2 times the rated current of the inverter.
9-8-2.Contactor
It's used to cut off power supply to prevent the failure to be expanded when the protection
function of the system is activated. The contactor can not be used to control the stop/start of the motor.
