Honeywell 2455R Series NC Thermal Switch, 110°C, 15A

The Honeywell 2455R Series NC Thermal Switch is a precision-engineered, flange-mounted safety component designed for reliable temperature monitoring and control. It operates as a normally closed (NC) switch, opening the circuit when the temperature reaches its calibrated switching point of 110°C. This automatic disconnection helps prevent overheating and potential damage in a wide variety of electrical and mechanical systems. The switch resets automatically, closing the circuit once the temperature falls below its reset point of 90°C, ensuring continuous protection without manual intervention.

Featuring a compact and robust flange mount housing, this thermal switch is easy to install in confined spaces. The inclusion of quick-connect terminals simplifies wiring and reduces installation time, making it a convenient choice for maintenance and assembly. With a substantial contact rating of 15A, it is capable of directly controlling or interrupting significant electrical loads, enhancing its versatility for different protective applications.

Key Specifications & Design
