Pass & Seymour WS4FBL3PTC Wide Slide 0-10V LED/Fluorescent Preset Dimmer, Tri-Color

The Pass & Seymour WS4FBL3PTC is a Wide Slide Series 0-10V Preset Dimmer built for Single Pole/3-Way operation with LED and fluorescent dimming drivers and ballasts. This Decorator-style device pairs an ON/OFF slide switch with a wider slider for smoother, easier dimming control, and it is rated for 0-10V, 4-wire dimming circuits at 120V 10A/277V 5A. Supplied as a Tri-Color device with an included built-in power pack, it is cULus Listed for reliable, code-compliant lighting control in commercial and residential applications.

Key Features

  • Combined Switch and Slider Control: Convenient operation combines an ON/OFF Decorator switch with a separate slider dedicated to dimming control.
  • Wider Slide Control: An enlarged slider makes dimming adjustment easier and more precise than standard-width sliders.
  • Decorator Styling: Sleek, ergonomic Pass & Seymour Decorator design matches other Decorator-style devices for a consistent wall appearance.
  • Labeled Low Voltage Pigtails: Low voltage pigtail leads are labeled separately to simplify and speed up installation wiring.
  • Locator LED: A green LED glows when the dimmer is in the OFF position, making the device easy to find in low light or darkness.
  • 0-10V Dimming Compatibility: Designed for use with 0-10V, 4-wire, 120V 10A/277V 5A LED and fluorescent dimming drivers and ballasts.

Pass & Seymour WS4FBL3P-TC – Frequently Asked Questions

1) Will the Pass & Seymour WS4FBL3P work with my 0-10V LED drivers?
Yes, the WS4FBL3P Wide Slide dimmer is built specifically for 0-10V, 4-wire dimming circuits, rated 120V 10A / 277V 5A, and works with both LED dimming drivers and fluorescent dimming ballasts. It is not a line-voltage phase-cut dimmer, so the fixture or driver must accept a 0-10V control signal.
2) Do I need a separate power pack to install this 0-10V dimmer?
No. A power pack is built into the WS4FBL3P, so no external power pack is required. That is the main install saver versus 0-10V controls that need a separate pack mounted in the ceiling or above the fixture.
3) Can this dimmer be used in a 3-way circuit with a second switch location?
Yes. The WS4FBL3P is configured for Single Pole/3-Way operation, so it can run a circuit on its own or be paired with a companion 3-way switch location. One dimmer controls the level; the other location handles on/off.
4) Is the WS4FBL3P listed for commercial code-compliant work?
The dimmer is cULus Listed, which covers both US and Canadian installations, and it is rated at 277V 5A as well as 120V 10A, so it suits commercial 277V lighting branch circuits as well as 120V residential work.
5) What colors does the Pass & Seymour WS4FBL3P come in, and what is TC?
Two ordering choices: WS4FBL3P-W in white, and WS4FBL3P-TC, a Tri-Color device that ships with ivory, light almond and white color options so one part number covers all three wall schemes. Finish is matte, matching Decorator-style devices on adjacent openings.
6) Is this a preset dimmer, and how does the switching work?
It is a preset device: an ON/OFF Decorator rocker switch handles switching and a separate wide slider sets the light level, so the lights return to the level you left the slider at. The wider slider gives finer adjustment than a standard-width slide control.
7) Will the WS4FBL3P fit a standard single-gang box and Decorator wallplate?
It uses Pass & Seymour Decorator styling, so it takes a standard Decorator (rocker-opening) wallplate and matches other Decorator devices already on the wall. Body construction is steel and thermoplastic, with a stated product height of 4.25 in, width 1.75 in and depth 1.25 in. Note that wallplates are ordered separately.
8) Can my electrician tell the low voltage leads apart on this dimmer?
Yes. The low voltage pigtail leads are labeled separately, so the 0-10V control pair is identified at the device and does not have to be traced out during rough-in or trim.
9) Will this dimmer be easy to find on the wall in a dark room?
A green locator LED glows whenever the dimmer is in the OFF position. Useful in conference rooms, corridors and bedrooms where the switch has to be found in the dark.
