How to select the correct NEMA contactor for a reversing motor application?
To select the correct NEMA contactor, match the NEMA size and continuous current rating to your motor's full-load amps and duty cycle. For reversing applications, ensure the contactor is mechanically interlocked to prevent simultaneous closure of forward and reverse contacts. Verify coil voltage matches your control circuit, such as the 120/240 V AC dual-rated coil on the Siemens 43EP32AA.
