United Electric B54-103 Temp Switch

United Electric B54-103 Temp Switch

The United Electric B54-103, also identified as the B54-103-9040, is a professional-grade immersion temperature switch engineered for reliable set-point control in boilers, heat exchangers, and industrial process tanks. This SPDT immersion switch features an adjustable temperature range of 0 to 225°F, allowing technicians to fine-tune thermal limits using the internal reference dial. Built with a brass immersion stem and a rugged NEMA 1 Lexan enclosure, this unit is designed to withstand the rigors of mechanical rooms while maintaining a repeatabilty of ±1% of the full scale range. The 15A SPDT switch output provides versatile wiring configurations for normally open or normally closed circuits, making it an essential component for industrial temperature monitoring and over-temperature protection. Its compact local-mount design ensures high responsiveness to fluid temperature fluctuations without the need for remote capillaries.

Key Benefits
  • Broad Operating Range: Precise 0 to 225°F set-point adjustment for diverse HVACR temperature control applications.
  • Durable Construction: Features a corrosion-resistant brass immersion stem and 3/8" OD bulb for direct media contact.
  • Internal Reference Dial: Simplifies field calibration and set-point verification for high-pressure industrial environments.
  • High Electrical Capacity: Rated for 15A at 125/250/480 VAC to handle heavy-duty immersion thermostat electrical loads.
  • Cross-Compatibility: The B54-103-9040 is a direct replacement for the standard B54-103, ensuring seamless system integration.
Common Questions Is the B54-103 suitable for domestic hot water systems? Yes, the 0-225°F range and SPDT configuration make it ideal for controlling circulator pumps or burner circuits in hydronic and domestic hot water applications. What is the maximum temperature limit for the sensor? The unit can withstand a maximum temperature of 250°F without damaging the immersion stem, though continuous operation should remain within the 225°F adjustable range. Can this switch be used to control two separate circuits? As an SPDT switch, it can toggle between two separate circuits (one normally open, one normally closed), though it acts on a single set-point.
