Intermatic Spring-Wound Timer 30 Min
The Intermatic FD430MW is a spring-wound mechanical timer offering a timing range of 0 to 30 minutes. It uses a DPST contact form rated for 20 A at 125 VAC and 10 A at 250 VAC or 277 VAC. The single-gang unit carries CSA and UL standards compliance.
Installers needing simple interval control
This timer suits applications requiring a straightforward, no-hold countdown up to half an hour. The white plastic knob provides manual setting without external power. Builders who need a hold feature, multi-gang configurations, or timing ranges beyond 30 minutes should look at alternative devices.
Handles up to 2 hp at 240 VAC
The contactor comfortably switches motor loads up to 1 hp at 120 VAC and 2 hp at 240 VAC. Resistive loads are managed within the 20 A at 125 VAC and 10 A at 250 VAC or 277 VAC limits. It runs out of capacity above these amperage or horsepower ratings.

Questions about this item
What voltage circuit and wire gauge do I need to power this FD430MW timer?
The timer handles up to 20 A at 125 VAC, 10 A at 250 VAC and 10 A at 277 VAC; choose wire rated for the circuit amperage and voltage you are using.
Can I run the timer on the same 240 V circuit as my older 1 hp motor starter?
Yes, the contactor is rated 2 hp at 240 V, so it will control a 1 hp motor on that voltage without exceeding its capacity.
How do I confirm the spring-wound mechanism is timing correctly after installation?
Set the knob to a known interval such as 30 min, energise the circuit and verify the load switches off when the dial reaches zero.
