United Electric 55 Series Temperature Switch
ABLE Instruments are United Electric’s Exclusive Representative for Sales and Service in the UK and Ireland, including the UE 55 Series, a rugged temperature electromechanical switch with external dial.
United Electric’s compact 55 bulb and capillary temperature switches are designed for use in food service appliances, oven control, and heat trace applications. They’re available in single or dual output versions, with a NEMA 4X enclosure or skeleton (open) construction, and with your choice of copper or stainless steel bulb and capillaries, in lengths from six feet (standard) to 50 feet (optional). The 55 Series temperature switch and control combine flexibility with compact size. They are cULus listed, cURus recognised, CE compliant.
Features:
- Single or dual 15A SPDT switch output, wired normally open or normally closed
- Copper or stainless-steel bulb and capillary
- Adjustable temperature ranges from -130° to 650° F
- NEMA 4X aluminium enclosure or skeleton construction, both with external dial for easy adjustment
- Setpoint repeatability: ±1% adjustable range
- Panel or surface mount for hassle-free installation
- cULus listed, cURus recognised, CE compliant
- Heat tracing models to protect pipes and vessels

|---|---|
Set Point Repeatability | ± 1% of adjustable range |
Shock | Set point repeats after 15 G, 10 millisecond duration |
Vibration | Set point repeats after 2.5 G, 5-500 Hz |
