Washroom exhaust fans, storage room lights and small motors get left running for hours in commercial buildings. The Intermatic FF330M is a commercial spring wound countdown timer that switches off after up to 30 minutes, rated 125-277 VAC with an SPDT contact. Because it needs no power or neutral to run, electricians swap it in for a standard wall switch on existing circuits.
Why electricians pick it
- Spring wound mechanism needs no neutral and no power to time.
- Works on 125 V through 277 V commercial circuits.
- SPDT contact can switch one load on during timing and a second load when time runs out.
- Handles incandescent, fluorescent, CFL and LED lighting plus fans and small motors.
- Supplied with a brushed-metal-look single-gang wall plate; CSA certified and UL listed.

Pro tip from the counter
Mind the rating drop on 277 V lighting circuits: the FF330M is good for 20 A at 125 VAC but only 10 A at 277 VAC, so add up the fixture load before putting a long 277 V run on one timer. Without a hold position it will always shut off, which makes it a poor choice where staff need a light left on all day.
Best for: washroom and janitor room exhaust fans, storage and mechanical room lights, commercial 277 V lighting circuits, energy-saving switch retrofits
