Product Identity
The Intermatic FF315M is a spring-wound mechanical timer designed for automatically limiting the run time of energy-consuming loads. It suits installers and facility managers who need a simple, non-electronic time control for single-gang mounting.
Interface Limits
The timer provides a 15-minute maximum timing cycle and carries a 1 hp rating at 120 V and a 2 hp rating at 240 V with an SPDT contact arrangement. It is cCSAus and RU listed, so it meets recognised North American safety standards for this class of control device.
Installation Notes
Single-gang mounting keeps the wiring straightforward for qualified electricians. The spring-wound mechanism requires no external power source, but the 15-minute limit means it cannot serve applications needing longer delays or programmable schedules.

Questions about this item
How does the 15 minute spring wound cycle actually limit equipment run time?
The spring wound mechanism counts down from 15 minutes and then opens the SPDT contacts to cut power to the connected load automatically.
What do the 1 hp at 120 V and 2 hp at 240 V ratings mean for motor loads?
Those horsepower ratings show the maximum motor size the contacts can switch reliably at each voltage without welding or excessive arcing.
What does the cCSAus listing cover for this timer?
The cCSAus mark confirms the timer meets both Canadian and US safety standards for electrical starters and contactors.
