Spring-wound countdown timer for AC loads

The Intermatic FF2H is a spring-wound countdown timer with a maximum setting of two hours and a single-pole single-throw contact rated for 125 to 277 volts AC. It suits installations that need automatic shut-off of energy-consuming equipment without an external power supply for the timer mechanism.

Manual operation replaces electronic programmers

The spring-wound mechanism eliminates the need for batteries or control-voltage wiring, so the timer functions during power interruptions and adds no standby consumption. Its single-gang format fits standard enclosures and the cCSAus and RU markings confirm compliance with North American safety standards for the listed voltages.

Fixed two-hour maximum limits scheduling flexibility

The mechanical dial cannot exceed two hours, so processes requiring longer delays or repeat-cycle operation need a different timer type. The SPST contact breaks only one conductor, which may not satisfy codes that require all ungrounded conductors to be disconnected for the load.

Questions about this item

Will the spring mechanism need lubrication or replacement after repeated 2-hour cycles?

The spring-wound mechanism is self-contained and requires no lubrication; it is rated for repeated 2-hour cycles without scheduled replacement.

What load limit will be reached first when the timer runs continuously at full rating?

The 1 hp at 120 V or 2 hp at 240 V motor rating is the first limit; the SPST contacts are sized to match that load.

Does the timer generate noticeable heat or noise when left running all day?

The mechanical movement produces a faint ticking sound and only minimal warmth during normal operation.
