Most common replacement contactor links above. You need to confirm basically three things before ordering a new contactor:
1 - Number of Poles (Most will be a 2 pole for standard 230v applications. Three pole would be for a three phase unit.)
2 - Coil Voltage (This is the power that supplies the electromagnet that pulls in the contactor. This is almost always 24 volts but there is a small chance it could be different.)
3 - AMPS (40A is the most common but yours could be larger. Be sure to get one at least as big or bigger than the amp rating of your current contactor.)
