Spring-Wound Timer 120/277V AC

This Intermatic FF12HHC is a spring-wound timer rated for 120/277V AC supply. It provides one gang and is rated at 1 hp at 120V and 2 hp at 240V. The silver finish suits standard electrical enclosures. It is designed for mechanical timing control in industrial and commercial settings.

Suits installers needing a mechanical timer

Electricians and maintenance staff who want a simple, self-contained timer for motor loads will find this unit fits. Buyers who need programmable digital schedules, multiple independent circuits, or battery-backed operation should look at other types because this model is a single-gang spring-wound mechanism only.

Mounts in a standard single-gang box

Installation follows normal single-gang wiring practice at 120V or 240V/277V. The spring mechanism must be wound fully before each timing cycle; forgetting to wind it is the most common reason the timer does not run. Verify the load does not exceed the 1 hp or 2 hp ratings to avoid contact damage.

Questions about this item

What voltage supply do I need for the Intermatic FF12HHC timer?

Can the timer control a 2 hp motor at 240V alongside existing equipment?

Yes, it is rated for 2 hp at 240V, allowing it to switch a motor of that size on the same circuit.
