Brand: Intermatic · SKU: FF312H · UPC: 078275184282 · Category: Controls & timers · Type: Spring-Wound Timers
Intermatic FF312H is a spring-wound countdown timer switch, commercial grade, rated 125-277 VAC at 50/60 Hz, single-pole, double-throw (SPDT), with a 12-hour maximum countdown and built without hold, finished in silver. Electricians and contractors install this timer switch in place of a standard wall switch to automatically shut off a connected load, such as a bathroom exhaust fan, heat lamp, or other fixture, after a set interval instead of leaving it running indefinitely. The mechanism is wound by hand to the desired setting and counts back down mechanically, switching the load off at the end of the interval. Its single-pole, double-throw contact arrangement allows the timer to control a single-pole load with a switched-over contact.
The Intermatic FF312H is rated 125-277 VAC and uses a SPDT switch configuration.
The Intermatic FF312H has a maximum countdown setting of 12 hour.
No, the Intermatic FF312H does not include a hold function; it runs only as a spring-wound countdown.
