United Electric B100-120 Temp Switch
The United Electric B100-120 is a heavy-duty single pole double throw (SPDT) temperature switch engineered for mission-critical industrial process control. This 100 Series mechanical switch provides a reliable interface for alarm, safety, and emergency shutdown functions in HVACR, boiler, and heat tracing systems. With an adjustable setpoint range of 0°F to 225°F and a maximum bulb temperature of 275°F, it delivers high-accuracy monitoring via a nickel-plated brass immersion stem. The unit features an internal reference dial in 10° increments, allowing for precise calibration within a rugged, epoxy-coated NEMA 4X cast aluminum enclosure. Designed for durability in corrosive conditions, this gasketed, weatherproof housing protects internal components from dust and moisture, making it a staple for contractors managing pumps, compressors, and fire suppression units.
Key Benefits for Contractors
- NEMA 4X Enclosure: Provides superior resistance to corrosion, moisture, and dust in demanding outdoor or wash-down environments.
- Flexible Integration: The SPDT snap-action switch can be wired normally open or normally closed to suit various system logic requirements.
- Precision Sensor: Equipped with a 9/16" OD x 1-7/8" immersion stem for rapid and accurate thermal response.
- Tamper-Resistant Design: Features an internal adjustment mechanism that prevents unauthorized setpoint changes on the job site.
- Technical Rating: Rated for 15A at 125/250/480 VAC, supporting high-capacity resistive loads common in commercial heating applications.
Common Questions
What is the maximum temperature limit for this switch?
The United Electric B100-120 has a maximum sensor bulb exposure limit of 275°F (135°C). Operating beyond this point can damage the thermal assembly.
Can this switch be used for freeze protection?
Yes, the 0°F to 225°F range makes it highly effective for freeze protection and heat trace monitoring in industrial piping and storage tanks.
How do I adjust the setpoint?
The setpoint is adjusted internally using the reference dial. This requires removing the gasketed cover, which prevents accidental or unauthorized adjustments during operation.
