United Electric B54-109 Temp Switch

United Electric B54-109 Temp Switch

The United Electric B54-109 is a rugged, NEMA 1 enclosure immersion temperature switch designed for reliable heavy-duty performance in HVACR and process monitoring. Featuring a brass immersion stem with a 3/8" OD and 2-1/8" length, this unit is engineered to manage high-fluid temperatures across an adjustable range of 200° to 425° F (93.3° to 218.3° C). As a 54 Series component, it utilizes a liquid-filled sensor that provides consistent repeatability to within ±1% of the full-scale range, even in environments prone to vibration or shock. The internal reference dial allows for precise field adjustments without compromising the Lexan housing's integrity. With SPDT snap-action contacts rated at 15A @ 125/250/480 VAC, this United Electric B54-109 Temp Switch is ideal for boilers, hydronic systems, and industrial heating equipment requiring dependable high-limit control or equipment cycling.

Key Benefits:
  • Broad Operating Range: Adjustable setpoint from 200° to 425° F, making it perfect for high-temperature demand applications.
  • Heavy-Duty Construction: Features a corrosion-resistant brass immersion stem and a shock-resistant black-finished Lexan enclosure.
  • Versatile Electrical Compatibility: The 15 Amp SPDT output easily integrates into standard 120V, 240V, or 480V control circuits.
  • Precise Calibration: Internal reference dial simplifies setpoint configuration for professional technicians in the field.
  • Industry Certifications: Meets cULus and CE standards for use in commercial and industrial settings.
Common Questions:

What is the maximum temperature limit for the sensor?
The sensing element can withstand temperatures up to 425° F. Exceeding this limit consistently may impact calibration accuracy.

Can this be mounted in any orientation?
While the B54-109 can be mounted in various positions using the immersion stem hex or bracket holes, vertical mounting is generally recommended to prevent moisture from pooling at the 7/8" conduit entry.

Is a thermowell required for installation?
A separable well (thermowell) is highly recommended for pressurized lines or systems requiring sensor maintenance without draining the process fluid.
