Spring-Wound Timer for Energy Loads
The Intermatic FD5M is a spring-wound timer designed to automatically limit the operating time of energy-consuming electrical loads. It is suited for installers and facility managers who need a mechanical time control without external power. The single-gang ivory unit mounts in standard enclosures. It carries cCSAus and RU safety listings.
1 hp at 120 V and 2 hp at 240 V
The timer is rated for 1 hp loads at 120 V AC and 2 hp loads at 240 V AC, with a maximum supply voltage of 277 V AC. It comfortably handles fractional-horsepower motors, lighting circuits and heating elements within those ratings. Loads exceeding the stated horsepower or voltage limits fall outside the device’s certified capacity. The mechanical spring mechanism provides a fixed timing range without electronic adjustment.
No accessories or software included
The product ships as the timer mechanism only; no programming tools, mounting hardware beyond the standard strap or software are bundled. Installation relies on conventional wiring practices and the device’s own terminal layout. There are no firmware updates or configuration utilities to manage. The absence of bundled accessories means the installer supplies any required wire connectors or cover plates.

Questions about this item
Will the 277V AC spring-wound timer control a 1 HP motor at 120V and a 2 HP motor at 240V in the same panel?
Yes, the timer is rated 1 HP at 120V and 2 HP at 240V, so it can handle both motor sizes on the appropriate circuits.
How can I verify the timer is limiting run time correctly after wiring it to a 277V load?
Set the dial, start the timer, and confirm the load shuts off automatically when the set time expires.
Does the ivory single-gang timer include a mounting box or cover plate, or must I supply them?
The timer itself is supplied; a compatible single-gang box and cover plate are not included and must be purchased separately.
