Intermatic FF6H Spring-Wound Timer
The Intermatic FF6H is a spring-wound timer designed for single-gang electrical installations. It operates on a 277V AC supply and carries cCSAus and cRUus safety certifications. The mechanism automatically limits the operating time of connected energy-consuming loads.
Installers needing simple time-limited control
This timer suits electricians and maintenance staff who need a mechanical delay function for lighting, ventilation or motor circuits rated up to 2 hp at 240V. It does not serve applications requiring programmable daily schedules, multi-gang configurations or electronic precision timing.
277V AC operating voltage
The unit is rated for 277V AC operation, a common commercial lighting voltage in North America. Horsepower ratings are 1 hp at 120V and 2 hp at 240V. Verify that the supply voltage matches this rating before installation.

Questions about this item
Will the 277 V AC spring-wound timer operate correctly on the 120 V or 240 V circuits I already have in the shop?
The timer is rated for 277 V AC; the listed horsepower ratings of 1 hp at 120 V and 2 hp at 240 V show the contact capacity at those lower voltages, but the coil itself requires 277 V AC to function.
How can I verify the timer is limiting run time as intended once it is wired in?
Set the dial to a short interval, energise the 277 V supply, and confirm the load switches off automatically when the spring-wound mechanism reaches zero.
Does the single-gang silver unit ship with a mounting box, wire connectors or a cover plate, or must I source those separately?
The supplied hardware is the spring-wound timer mechanism only; a 1-gang box, cover plate and wiring accessories are not included and must be purchased separately.
