Intermatic 208/277 Volt, 60 Hz Replacement Time Clock Motor, WG1573-10D

The Intermatic WG1573-10D is the replacement clock motor for Intermatic mechanical time switches running on 208 or 277 volt, 60 Hz power. It is the genuine Intermatic part.

What it fits

Intermatic lists it for T104 timers and for the T100, T170, T180, T100R201, T100R301, WH30 and WH40 series timer switches. If the timer runs on 125 volt, that takes the separate 125 volt motor, so check the label on the mechanism before ordering.

About the part number

On Intermatic motors the digits after the dash are the factory revision, not a different part. WG1573 is the motor, and this is the -10D revision, so it goes in where an older WG1573-5 came out.

Installing it

The motor carries fixed tab connectors that slide over the connection poles on the timer, so the swap is mechanical. It is a high torque motor built to keep the mechanism turning in heavy duty service.
