4.6 Bypass Contactor
MCD 500 soft starters with model numbers MCD5-0021B - MCD5-0215B are internally bypassed and do not require an external bypass contactor.
MCD 500 soft starters with model numbers MCD5-0245C - MCD5-1600C are not internally bypassed and may be installed with an external bypass contactor.
Select a contactor with an AC1 rating greater than or equal to the full load current rating of the connected motor.
4.7 Main Contactor
A main contactor must be installed if the MCD 500 is connected to the motor in inside delta format and is optional for in-line connection. Select a contactor
with an AC3 rating greater than or equal to the full load current rating of the connected motor.
4.8 Circuit Breaker
A shunt trip circuit breaker may be used instead of a main contactor to isolate the motor circuit in the event of a soft starter trip. The shunt trip mechanism
must be powered from the supply side of the circuit breaker or from a separate control supply.
4.9 Power Factor Correction
If power factor correction is used, a dedicated contactor should be used to switch in the capacitors. Power factor correction capacitors must be connected
to the input side of the soft starter. Connecting power factor correction capacitors to the output side will damage the soft starter.
