The Intermatic WG1573-10D time clock motor is very sturdy with a high torque. Fixed tab connectors easily slip over the timer connection poles for simple installation. This WG1573-10D replacement motor is for use with the Intermatic T102, T104 and WH40 time switches. 208/277 Volts and 60HZ. The motor itself is labeled WG1573-5, but when the (2) 11-inch leads are attached the product then becomes WG1573-10D.
