Intermatic FF4H is a mechanical spring-wound countdown timer switch, built for commercial control applications where a load needs to run for a set interval and then shut off automatically. As a spring-wound mechanical timer, FF4H winds up to run for a maximum of 4 hours, switches on a SPST contact arrangement, and is rated for 125-277 VAC at 50/60 Hz. This version does not include a hold position, so it operates strictly on the wound countdown cycle. The unit has a silver finish. Intermatic lists this as a spring-wound timers product in the spring wound timers family, sold as a single each. It is used by electricians and contractors on commercial jobs that call for a mechanical, spring-wound shutoff on a timed circuit.
