Intermatic FM/1QTUZ-120U Timer

The Intermatic FM/1QTUZ-120U is a heavy-duty electromechanical timer module engineered for seamless integration into OEM panels, HVACR control circuits, and industrial equipment. This 120V quartz drive timer features a 72-hour battery backup (carry-over) to maintain synchronous timing accuracy during power interruptions, ensuring your 24-hour or 7-day schedules remain intact. Built with a robust SPDT switch rated for 21 Amps resistive and up to 1 HP at 120V, this module handles high-demand loads including refrigeration compressors, circulation pumps, and air movement ventilation systems.

The unit utilizes captive trippers for easy interval setting?15-minute increments for the 24-hour dial?providing precise control without the risk of losing pins. Designed for space-constrained applications, the compact panel mount housing features standard 1/4-inch quick-connect terminals for rapid field installation. Whether managing generator exercising or complex lighting arrays, the FM1 series module delivers industrial-grade switching reliability and noise immunity for the most demanding technical environments.

Key Benefits

• Quartz Accuracy: Integrated battery backup ensures scheduled cycles continue without manual resetting after a power failure.
• High Amperage Capacity: The 21A SPDT contact configuration supports both normally open and normally closed logic for versatile system integration.
• Simplified Programming: Captive trippers allow for fast, visual schedule adjustments that cannot be lost or misplaced.
• Universal Mounting: Compact 2.36-inch square footprint fits standard interchangeable timer cutouts in most control panels.

Common Questions

• What is the difference between this and a synchronous model? This quartz model includes a battery backup to keep time during outages, whereas synchronous models stop the clock when power is lost.
• Can this be used for both 24-hour and 7-day scheduling? Yes, the FM/1 series design supports multi-functionality depending on the specific dial configuration and captive tripper settings provided.
• What electrical connections are required? The module uses four 1/4-inch male tabs for power (120V) and the SPDT switch output.
