Intermatic FD12HC Timer

The Intermatic FD12HC is a heavy-duty 12-hour spring wound timer engineered for precise control of HVAC systems, lighting, and industrial motors. As a SPDT spring wound timer, this unit offers versatile wiring configurations, allowing for both normally open (NO) and normally closed (NC) applications. Designed to replace standard wall switches, it features a robust mechanical countdown timer mechanism that does not require electricity to operate, making it ideal for high-reliability environments where electronic components might fail. This industrial wall timer supports 20 Amps at 125 VAC and 10 Amps at 277 VAC, providing the durability needed for heavy-duty motor control. The ivory finish and commercial grade timer build Ensure it handles the rigors of frequent manual adjustments. Whether you are managing exhausting fans or heating elements, the manual countdown switch provides a dependable "hold" feature to maintain circuit state beyond the standard timing cycle.

• Versatile SPDT Circuitry: Provides flexible wiring options for diverse control requirements, reducing the need for multiple SKUs on the truck.
• Inductive Load Rating: Optimized for motor and transformer loads common in commercial mechanical rooms.
• No Neutral Required: Simplifies installation in older buildings where neutral wires are absent at the switch box.
• Rugged Construction: Press-on knob and heavy-duty dial plate withstand daily use in high-traffic environments.
