Intermatic FF6H Timer

The Intermatic FF6H is a heavy-duty 6-hour spring wound timer engineered for precise manual override control in demanding commercial and industrial environments. This SPST (Single Pole Single Throw) interval timer is designed for high-amperage loads, featuring a 20 Amp inductive rating at 125 VAC and a 7-HP motor rating at 240 VAC. The mechanism replaces standard toggle switches to provide energy-saving timed-off control for exhaust fans, lighting circuits, and heavy-duty blowers. Built with a rugged brushed aluminum faceplate, the FF6H utilizes a commercial-grade metal construction that withstands repetitive use in mechanical rooms and job sites. The twist-to-set mechanism allows for immediate operation without the complexity of digital programming or the need for a neutral wire, making it a drop-in solution for contractors retrofitting older systems. Its teardrop dial provides clear visibility of the remaining countdown, ensuring accurate power management and preventing equipment burnout from excessive runtimes.

• High-Amperage Capacity: Rated for 20A resistive and 7-HP motors, eliminating the need for additional contactors in many applications.
• No Neutral Required: Simplifies installation in older electrical boxes where a neutral wire may not be present.
• Durable Aluminum Finish: Provided with a brushed metal faceplate and commercial-grade metal dial for long-term reliability in high-traffic areas.
• Universal Compatibility: Fits into standard single or multi-gang electrical boxes as a direct decorator wall plate replacement.
• Simplified Control: Offers a straightforward 6-hour countdown range for controlling ventilation, heating, or process equipment.
