Intermatic FF12HHC Timer

The Intermatic FF12HHC is a heavy-duty 12-hour spring wound timer designed for commercial and industrial applications requiring precise, manual count-down control. Featuring a SPST switch configuration with a stay-on hold feature, this mechanical interval timer allows contractors to bypass the timing cycle for continuous operation when necessary. Built with a robust brushed metal finish, the FF12HHC wall switch is engineered to handle high-inductive motor loads up to 1 hp at 125 VAC, making it an ideal choice for HVAC ventilation control, commercial lighting, and heavy-duty fans. This industrial countdown timer fits directly into standard single or multi-gang electrical boxes and includes a professional-grade dial plate and knob. The simplified two-wire connection ensures a fast, reliable installation for field technicians, while the mechanical spring-driven movement eliminates the need for a neutral wire, providing a dependable solution for commercial electrical retrofits.

• Universal Compatibility: Fits standard toggle-style wall plates for seamless integration into existing electrical setups.
• Manual Hold Feature: Integrated "Hold" position allows for constant power without restarting the timing mechanism.
• High Load Capacity: Rated for 20 Amp resistive loads and 7 Amp tungsten, ensuring durability under heavy cycling.
• Reliable Mechanical Operation: Spring-wound design functions independently of power outages for consistent performance.
• Contractor-Grade Construction: Metal faceplate and rugged internal components withstand frequent use in demanding environments.

How do I wire the FF12HHC for a 240V circuit?
The Intermatic FF12HHC is a single-pole, single-throw (SPST) switch. For 240V motor applications, this timer breaks only one leg of the power supply. Ensure your installation complies with local electrical codes regarding disconnect requirements for high-voltage loads.

Can the hold feature be disabled if not needed?
The hold feature is built into the dial rotation. To prevent users from leaving the device in the "on" position indefinitely, you should specify an FF series model without the "H" designation in the part number.

Will this timer work for low-voltage signal applications?
While primarily used for line-voltage loads, the dry contact SPST switch can be utilized for low-voltage control circuits, provided the current draw does not exceed the mechanical rating of the switch contacts.
