Intermatic FF15MC Timer

The Intermatic FF15MC is a rugged 15-minute SPST spring-wound timer engineered for commercial-grade reliability in HVACR and electrical applications. As the direct replacement for A515M, this mechanical countdown switch fits seamlessly into a standard 2-1/2 inch deep vertical junction box, requiring no neutral wire for operation. The single-pole single-throw configuration is rated for 20 Amps at 125 VAC and up to 2 HP at 240 VAC, making it a versatile solution for controlling high-draw loads such as exhaust fans, lighting control, and small motors. The brushed metal look plate provides a durable finish that meets NEC requirements while the teeter-type terminals simplify field wiring. Designed for intermittent use, this manual twist timer ensures energy efficiency by automatically breaking the circuit at the end of the selected timing cycle without the need for an external power source.

• Universal Compatibility: Serves as a drop-in replacement for Intermatic A515M and fits most standard single-gang or multi-gang wall boxes.
• Simplified Installation: Features up-front teeter-type terminals for fast, secure wire connections under pressure plates.
• Mechanical Precision: Operates as a 15-minute countdown timer without requiring electricity, ensuring functionality regardless of power status.
• High Load Capacity: Rated for motor control up to 1 HP at 120V or 2 HP at 240V for robust performance in mechanical rooms.
• Code Compliance: Includes a silver metal dial plate and black plastic knob that meet commercial aesthetic and safety standards.

Is a neutral wire required for the FF15MC?
No, this is a mechanical spring-wound timer that interrupts the "hot" leg of the circuit and does not require a neutral connection.

Can I use this timer for a 3-way lighting circuit?
The FF15MC is an SPST switch; for 3-way applications, you would typically require an SPDT model like the FF15MH.

What are the terminal ratings for this unit?
The unit handles 20A resistive at 125V, 10A at 250/277V, and 7A tungsten at 125V for diverse load types.
