Spring-Wound Timer 30 min
The Intermatic FD30MH is a spring-wound timer that runs from 0 to 30 minutes without external power. It suits installers who need a simple, mechanical time control for lighting, ventilation or small motor loads in residential or light-commercial settings.
Single-gang wall installation
The unit fits a standard single-gang box and wires in series with the load. Because it is purely mechanical, there is no programming or battery to maintain; the only common issue is over-tightening the winding knob, which can damage the internal spring.
1 hp at 120 V, 2 hp at 240 V
The contacts are rated for 1 hp on 120 V circuits and 2 hp on 240 V circuits, covering most fractional-horsepower fans, pumps and heaters. Loads above those horsepower ratings or multi-gang switching requirements fall outside the device’s capacity.

Questions about this item
How can I confirm the timer is operating correctly after wiring it at 120V?
The timer should click as the spring unwinds and cut power to the load when the dial reaches zero, indicating the internal mechanism is functioning.
What components are included with the FD30MH and what must be purchased separately?
The unit includes the spring-wound timer mechanism and ivory dial; mounting hardware, wire connectors and an enclosure are not supplied.
Which version should I select for a 240V circuit?
The FD30MH is rated 2 hp at 240V, so the single-gang model listed is the correct choice for that voltage.
