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.
