Spring-Wound Timer 30 Min SPDT
The Intermatic FF330M is a spring-wound timer rated for 30 minutes of operation. It provides a single-gang SPDT switching function designed to automatically limit the run time of energy-consuming loads. The unit carries cCSAus and RU safety standards and is finished in silver. It suits applications where a simple mechanical time control is required without external power.
Voltage and Load Rating Check
Verify that the supply voltage matches either 120 V or 240 V operation before installation. The timer is rated at 1 hp at 120 V and 2 hp at 240 V, so confirm the connected motor or load does not exceed these horsepower limits. Ensure the single-gang mounting format fits the intended enclosure or panel cut-out. The device is restricted from sale in certain states, so check local regulations before ordering.
Mechanical Operation and Standards
The spring-wound mechanism requires no batteries or control voltage, so it operates independently of the mains once set. This mechanical action directly drives the SPDT contacts to open or close the circuit at the end of the 30-minute period. Compliance with cCSAus and RU standards means the timer meets recognised North American safety requirements for electrical starters and contactors. No additional accessories or software are bundled with the unit.

Questions about this item
Does the spring-wound timer include mounting hardware or must it be purchased separately?
The timer is supplied as a single-gang unit; mounting screws and a suitable enclosure are not included and must be sourced separately.
Should I select the 1 hp at 120 V or 2 hp at 240 V rating for my circuit?
Choose the rating that matches your supply voltage — 1 hp on a 120 V circuit or 2 hp on a 240 V circuit — because the SPDT contacts are rated for both.
What does the 30-minute maximum setting actually control in practice?
The spring-wound mechanism limits the load to a maximum run time of 30 minutes before the contacts automatically open.
