Spring-Wound Timer for 277V AC Circuits
The Intermatic FF5MH is a spring-wound timer designed to automatically limit the operating time of energy-consuming loads on 277V AC circuits. It provides a single-gang switching solution for controlling motors and other equipment. The unit carries cCSAus and RU safety standards for compliant installations.
Suited for Single-Gang Motor Control Applications
This timer suits installers needing a mechanical time-limit switch for 120V or 240V motor loads up to 1 hp and 2 hp respectively. It is not intended for applications requiring electronic programming, multiple independent circuits, or control of loads exceeding the stated horsepower ratings. Buyers needing digital scheduling or multi-gang configurations should consider alternative devices.
Mechanical Operation Requires No External Power
The spring-wound mechanism operates without external control voltage, simplifying wiring in retrofit or new installations. Its automatic limiting function helps reduce energy consumption by ensuring loads run only for the set duration. The silver finish provides a durable surface for industrial or commercial environments.

Questions about this item
What voltage supply must the installation provide for the 277V AC timer to operate?
The timer is rated for 277V AC, so the circuit must deliver that voltage.
Can the 1 hp at 120V and 2 hp at 240V ratings be used on the same 277V circuit?
Those horsepower ratings apply at 120V and 240V respectively; they are not valid at 277V.
How can I verify the timer is limiting the load automatically after wiring it?
Set the spring-wound dial, energise the circuit, and confirm the load disconnects when the set time expires.
