Intermatic FF30MH Spring-Wound Timer 30 Min SPST Silver
A spring-wound timer that automatically limits run time to 30 minutes for energy-consuming loads
- Automatically limits load run-time to 30 minutes
- Spring-wound mechanism operates without external power
- SPST contacts switch up to 1 hp at 120 V
- SPST contacts switch up to 2 hp at 240 V
- cCSAus and RU safety standards certified
Spring-Wound Timer for Automated Load Control
This Intermatic FF30MH timer uses a mechanical spring mechanism to automatically limit the operating time of energy-consuming loads. It is suited for applications where a simple, non-electronic time control is preferred. The single-gang design fits standard electrical installations. It carries cCSAus and RU safety certifications.
30 Minute Cycle with 1 hp at 120V and 2 hp at 240V
The timer provides a maximum delay of 30 minutes per winding cycle. It handles motor loads up to 1 horsepower at 120 volts and up to 2 horsepower at 240 volts. Loads exceeding these ratings or requiring longer continuous run times fall outside the device's capacity. The single-pole single-throw action switches one circuit on or off.
Mechanical Operation Limits
As a spring-wound device, it requires manual winding for each timing cycle and does not retain a schedule during power loss. The SPST contact configuration controls only one circuit path. It is not designed for loads requiring multi-pole switching, programmable daily schedules, or electronic precision timing. Orders of $75 or more ship free from the supplier.

Questions about this item
Will the FF30MH spring-wound timer control a 1 hp motor at 120V alongside my existing contactor?
Yes, the timer is rated for 1 hp at 120V and 2 hp at 240V, so it can switch a 1 hp motor on a 120V circuit with your contactor.
How can I verify the 30-minute spring-wound timer is operating correctly after installation?
Set the dial to a short interval, energise the circuit, and confirm the load switches off automatically when the spring runs down at the marked time.
Does the FF30MH timer include mounting hardware or must I purchase a gang box separately?
The timer is a single-gang unit; mounting screws and a compatible gang box are not included and must be sourced separately.
