United Electric E54-D23BC-0500 Temp Switch

The United Electric E54-D23BC-0500 is a heavy-duty industrial temperature switch designed for high-limit monitoring and critical shutdown applications. Featuring an adjustable setpoint range of 150 to 650°F, this 54 Series control utilizes a liquid-filled copper bulb and capillary sensor to provide responsive and repeatable actuation. The 6-foot capillary offers significant installation flexibility for remote sensing in boilers, ovens, and thermal processing systems. As a single-pole double-throw (SPDT) switch, it provides versatile 15-amp electrical control for both normally open and normally closed circuits. The unit is housed in a rugged, black-finished Lexan NEMA 1 enclosure, making it a reliable choice for indoor HVACR environments and OEM machinery. With an internal reference dial for precise field adjustments and a narrow deadband, the E54-D23BC-0500 ensures accurate temperature regulation and system protection without the marketing fluff found in consumer-grade controls.
