Intermatic FF430M Spring-Wound Timer
The Intermatic FF430M is a spring-wound timer rated for 30 minutes of operation. It uses a DPST contact arrangement to switch both poles simultaneously. The unit carries cCSAus and RU standards markings. It is suited for installations that require automatic time limiting on energy-consuming loads without external power for the timing mechanism.
30-Minute Mechanical Timing Cycle
The single specification that decides fit is the fixed 30-minute maximum timing range. The spring-wound mechanism provides a purely mechanical countdown with no electrical supply needed for the timer itself. The DPST switching handles 1 hp at 120 V and 2 hp at 240 V. Buyers who need adjustable or longer timing intervals, or who require electronic programmability, will find this model unsuitable.
Sustained Load Switching Behaviour
Under continuous operation the mechanical spring drives the timing cam through the full 30-minute cycle without drift. The DPST contacts are rated for the stated horsepower loads at 120 V and 240 V throughout the cycle. The timer automatically opens both poles at the end of the wound period, limiting energy consumption. No thermal derating or electronic component ageing applies to the spring-driven mechanism.

Questions about this item
What does the 30 minute spring-wound cycle actually control in a real installation?
It automatically limits the run time of connected loads up to 30 minutes before switching them off.
How do the 120 V and 240 V horsepower ratings limit what I can switch?
The timer handles up to 1 hp at 120 V and up to 2 hp at 240 V, so motor loads must stay within those ratings.
What does the single-gang DPST body need to fit into?
It mounts in a standard single-gang enclosure and uses a double-pole single-throw switching arrangement.
