Honeywell 2455R Series Thermal Switch, NO 120°C Reset 100°C

The Honeywell 2455R Series Thermal Switch is a precise and reliable temperature-activated safety component, designed for high-current applications. This model features a normally open (NO) contact configuration, which closes the circuit when its specific switching temperature of 120°C is reached, and automatically resets once the temperature drops below 100°C.

Constructed with robust materials, the switch offers a generous contact rating of 15A, making it suitable for directly controlling heaters, motors, or fans without the need for additional relays in many circuits. This capability simplifies system design and enhances reliability. The sensor is housed in a durable flange mount housing, allowing for secure and stable mechanical installation onto surfaces for accurate temperature sensing.

Quick connect terminals on the sensor provide a fast, tool-free wiring process, reducing installation time and improving connection reliability. With its compact dimensions of 33mm x 22mm x 2mm, this thermal switch can be integrated into space-constrained applications without compromising performance.

Its primary function is to provide over-temperature protection, automatically interrupting or enabling a circuit based on the ambient temperature to prevent equipment damage or hazardous conditions. The reliable reset mechanism ensures continuous, automatic operation without manual intervention, making it an ideal 'fit and forget' safety device for a wide range of industrial and commercial equipment.
