Intermatic Spring-Wound Timer 5 Min FD5MW
The Intermatic FD5MW is a spring-wound mechanical timer rated for a 0 to 5 minute timing range. It uses a single-pole single-throw contact form and fits a single-gang enclosure with a white faceplate and plastic knob. It is suited for installers who need a simple, non-electronic timing control for lighting or motor loads.
Voltage and Current Limits
The contactor carries 20 A at 125 VAC, 10 A at 250 VAC and 10 A at 277 VAC. Motor loads are rated at 1 hp at 120 V and 2 hp at 240 V. It carries CSA and UL listings. The timer has no hold feature, so the circuit opens automatically when the set time expires.
Timing Capacity and Headroom
The 5-minute maximum setting covers short-cycle duties such as fan run-on, pump priming or brief lighting sequences. It runs out for processes that need longer delays or repeat-cycle operation. The single-gang format and lack of a hold function mean it cannot maintain a closed circuit beyond the wound interval without manual reset.
