Spring wound countdown timer 4 hour max SPST 125-277 VAC - decorator style no hold white - Intermatic FD4HW
Mechanical decorator-style countdown timer for lights, fans, motors and other energy-consuming loads, with a 4 hour maximum setting and SPST switching at 125-277 VAC. Commonly used where automatic shut-off is needed in bathrooms, storage rooms and similar spaces; wall plate typically sold separately.
What this product is for
The Intermatic FD4HW is a spring wound in-wall countdown timer for automatically turning loads off after a selected run time. It is designed for decorator-style wall switch locations and is commonly used to control exhaust fans, lighting, motors and similar loads where run-on time should be limited.
Use for
- Bathroom exhaust fans
- Closet, storage room and utility room lighting
- General-purpose automatic shut-off control for compatible 125-277 VAC loads
- Retrofit replacement for a standard decorator wall switch in single-gang or multi-gang installations
Avoid for
- Applications requiring a maintained ON hold position
- Loads that could create a safety risk if switched off by timer
- Sunlamps, saunas or similar applications identified by the manufacturer as unsuitable
- Installations where a wall plate is required but not separately specified
Best for
Best for electricians and contractors who need a simple mechanical auto-off timer without requiring operating power for the timing mechanism. It suits washrooms, fan control points and other spaces where occupants may leave loads running unnecessarily.
Installed in
Typically installed in standard wall switch boxes in residential, commercial and light industrial interiors. The timer is made to replace standard or decorator-style single- or multi-gang wall switches.
Why this product exists
This timer helps reduce unnecessary run time on fans and lighting by automatically breaking the circuit at the end of the timing cycle. Because it is spring wound, it does not require electricity to operate the timer mechanism, which can simplify selection where electronic timer features are not needed.
Compared with similar products
Compared with electronic countdown timers, the FD4HW uses a mechanical spring wound design and does not rely on powered electronics for timing. Compared with models that include a hold feature, this version is intended for timed operation only and does not provide a maintained ON position. A 4 hour maximum setting makes it suitable for longer fan or lighting run times than short-interval bathroom timers.
