Brand: Intermatic | Manufacturer Part Number: FF460M | Big Frog Supply SKU: FF460M
Product Overview
The Intermatic FF460M is a commercial-grade 60-minute spring-wound countdown timer with DPST switching and a silver brushed-metal-look wall plate. Turning the knob sets an operating period of up to one hour, after which the timer opens both switched poles. This makes it suitable for approved two-pole loads or circuits that require simultaneous disconnection through a double-pole, single-throw control.
The countdown mechanism is mechanical and does not require electrical power to keep time, so no neutral connection is needed. The FF460M can automatically limit operating time for compatible fans, lighting, motors, heaters, and other energy-consuming equipment. It does not include a HOLD position; the connected load turns off when the selected countdown expires. The single-gang mechanism can also be used in an approved multi-gang arrangement.
