Spring-Wound Timer for Motor Loads
The Intermatic FF32H is a spring-wound timer rated for one horsepower at 120 volts and two horsepower at 240 volts. It uses a single-gang SPDT switch with silver contacts to automatically limit run time for energy-consuming loads. The mechanical design requires no external power source to operate the timing mechanism. It carries cCSAus and RU safety certifications.
Two-Hour Maximum Cycle Under Load
The timer provides a maximum run time of two hours per winding cycle before the spring fully unwinds. Because the mechanism is purely mechanical, the timing remains consistent regardless of voltage fluctuations or ambient temperature changes that affect electronic timers. The silver contacts are rated for the full horsepower load at both 120 and 240 volts without derating for sustained operation. There is no minimum load requirement for the contacts to function reliably.
Single-Gang Wall Mount Installation
The unit fits a standard single-gang electrical box and mounts with two screws. The spring-wound knob must be turned fully clockwise to the desired time setting; turning it counter-clockwise or forcing it past the two-hour stop damages the mainspring. Silver contacts should not be filed or cleaned with abrasives as this removes the contact plating. No neutral connection is required for the timer mechanism itself, only for the load circuit.

Questions about this item
Does the spring-wound mechanism produce any audible ticking or heat during continuous 2-hour cycles?
The timer uses a purely mechanical spring-wound movement with no motor, so it runs silently and generates no measurable heat during its 2-hour cycle.
What voltage supply and wiring configuration are required to connect the SPDT silver contacts?
The contacts are rated for 1 hp at 120 V and 2 hp at 240 V, single-gang, and accept standard line-voltage wiring for SPDT switching.
Will this timer fit in the same enclosure and match the contact spacing of an older Intermatic FF series unit?
It is a single-gang, spring-wound unit with SPDT silver contacts built to the same cCSAus and RU standards as earlier FF models.
