CONTACTOR RELAY MC-32A

MC32A is a contactor (often LS / LG brand) used to switch the motor’s power.
It is designed to work with MT-32 series overload relays like your MT323H.

Typical features of an MC32A contactor:

Suitable for motors up to about 3–5 HP (depending on voltage)
Good for D.O.L starting
Comes with:

• 3 power poles (for 3-phase)

• Aux contacts (optional)

• Coil voltage (e.g., 220 V, 110 V depending on your setup)

How MC32A + MT-32 Work Together

These two parts make a complete motor starter:

MC32A (contactor)
+ cuts or applies power to the motor

MT-32 (thermal overload)
+ protects the motor from over current

MC32A + MT323H = D.O.L Starter for your motor
