Common Technician Questions Can the PE-05-2301 replace a single-pole contactor in a 240V system

it is industry best practice to match this motor with a new capacitor of the microfarad (µF) rating specified on the 70021531 nameplate to ensure proper phase shift and starting torque

a higher voltage rating is always acceptable as long as the microfarad (MFD) ratings match the motor's requirements
