Intermatic WG1573-10D 60-Hz Replacement Clock Motor - High Torque

In this review the Intermatic WG1573-10D replacement clock motor is evaluated for installers and home technicians who need a dependable time switch motor. The bottom line: this motor is built for durability and torque, making it a good choice when replacing worn or weak clocks in compatible Intermatic time switches. Installation is straightforward for anyone comfortable with basic wiring, and the fixed tab connectors and 11-in leads make swapping the old motor quick. For those who need a direct, heavy-duty replacement for specific Intermatic T and WH series timers, this motor delivers reliable performance.

Key Features

• High torque design: Provides the force needed to drive worn timers and maintain accurate switching under load.
• Fixed tab connectors: Slip-over tabs simplify installation by fitting directly on timer connection poles without special tools.
• 11-in lead wires: Two pre-attached 11 in leads allow flexible routing and secure connections for models that require external leads.
• 60-Hertz operation: Matches standard 60 Hz systems so timing remains consistent with line frequency for on/off schedules.
• 208/277 V rating: Compatible with higher-voltage commercial and industrial circuits where those Intermatic switches are used.
• Labeling note: Motor is labeled WG1573-5 but becomes WG1573-10D when the additional leads are attached, clarifying identification during replacement.

Who It's For

This motor is best for electricians, facility maintenance staff, and DIYers familiar with replacing parts in time switches, especially those working on Intermatic T102, T104 and WH40 series timers. It is a practical, no-frills replacement when the original clock motor has failed or lost torque and the application calls for 208/277 V and 60 Hz operation.

It is not intended for universal use across all timer brands or frequencies; users with 50 Hz systems or non-Intermatic models should look for a motor specified for those voltages and frequencies. Also, if a custom mounting or nonstandard connector is required, this direct-replacement motor may not be a match.

Pros & Cons

Pros

• High torque output restores reliable operation to aging time switches that struggle to advance.
• Fixed tab connectors and pre-attached 11 in leads speed up installation and reduce handling time.
• Built for 208/277 V and 60 Hz, matching common commercial circuits where these timers are used.

Cons

• Label discrepancy (motor marked WG1573-5) can confuse identification until leads are attached and it becomes WG1573-10D.

Our Verdict

The Intermatic WG1573-10D is a practical, rugged replacement clock motor for the specified Intermatic timers, offering high torque and convenient connectors that make installation straightforward. For professionals and competent DIYers needing a direct replacement in 60 Hz, 208/277 V systems, it represents solid value because it restores reliable timing without extra parts. Those needing cross-brand compatibility or different frequency ratings should choose a motor specified for their system instead.

Frequently Asked Questions

Will this motor fit my Intermatic T104 timer?
Yes, the WG1573-10D is specified for use with Intermatic T102 and T104 time switches and will replace the original motor in those models.

What voltage and frequency does this motor require?
The motor operates at 60 Hz and is rated for 208/277 V, suitable for those commercial circuit voltages.

Why does the motor label differ from the model name?
The motor itself is labeled WG1573-5, and when the two 11 in leads are attached the assembly becomes WG1573-10D; the extra leads are the distinguishing feature.
