Shop heaters, pool pumps and ventilation fans in common areas get left running long after everyone leaves. The Intermatic FF6H is a commercial spring-wound countdown timer that replaces a single-gang wall switch and shuts the load off after up to 6 hours. It runs on 125-277 VAC with no power needed to time, and the no-hold dial means nobody can park it permanently on. Intermatic states FF series timers are not for sunlamps, saunas or any load that could cause injury if timed incorrectly.
Why facility managers pick it
- 0-6 hour countdown, then the SPST contact opens the circuit.
- No HOLD position, so the load always times out (the FF6HH adds a hold).
- Spring-wound mechanism needs no electricity to time.
- Resistive ratings of 20 A at 125 VAC and 10 A at 277 VAC; motors to 2 HP at 250 VAC.
- Fits a standard 2-1/2 in deep box, with a brushed-metal-look plate.

Pro tip from the counter
Pick the no-hold FF6H for shared spaces like rental garages, gyms and community rooms where you want every run to end on its own. Where staff genuinely need an all-day override, the FF6HH with a HOLD position is the better fit, but expect it to be left on hold.
Best for: shop and garage heaters, pool and hot tub pumps, common-area ventilation fans, commercial run-time limits on lighting
