Description
Ensure reliable, automatic control of lighting, fans, motors, and other loads with the Intermatic FF312H — a rugged, electricity-free mechanical timer designed for energy-saving convenience in commercial and residential applications. Replace a standard wall switch with this timer to automatically limit on-times and help manage energy and run times effectively.
Key Features
-
Fully Mechanical, No Power Needed: The FF312H uses a spring-wound mechanism — no external power or batteries required — making it ideal for simple, maintenance-free installations.
-
12-Hour Auto-Off Timer: Set once, and the timer automatically switches the circuit off after up to 12 hours — perfect for lights, fans, heaters, motors, or ventilation systems that don’t need continuous operation.
-
Wide Voltage & Load Compatibility (125–277 VAC): Works across a broad range of standard supply voltages, making it versatile for residential, commercial, and light-industrial use.
-
SPDT Contact Configuration: Single-Pole Double-Throw (SPDT) contacts allow flexible control of circuits (normally open or normally closed), enabling straightforward replacement of a standard switch without rewiring.
-
Compact, Standard Wall-Switch Form Factor: Installs easily in a standard single-gang wall box — replacing a conventional light switch or outlet — with standard mounting and teeter-type terminals.
-
Energy Savings & Load Management: Automatically limits run times for fans, lighting, motors, heaters, and other load-based devices — helping reduce wasted energy and wear on equipment.
