Honeywell Bi-Metallic Thermostat SPST-NC 75°C Closing Temperature 186°C Max Operating Temperature 10A 2455RP-91000437

Honeywell 2455RP-91000437 Bi-Metallic Thermostat is a reliable temperature-responsive device designed for industrial, HVAC, and electrical applications. It operates as a normally closed single-pole single-throw switch that opens at a preset trip temperature of 75°C, ensuring equipment protection from overheating by interrupting the circuit at this threshold. With a robust maximum operating temperature capability of 186°C, this thermostat withstands high-stress thermal conditions without failure.

The device supports a contact current rating of 10A and an AC voltage rating of up to 250V, enabling its use in moderate load switching scenarios within mains AC circuits. Its automatic reset function restores the circuit when temperatures fall below the release point, allowing seamless system restarts without the need for manual intervention.

Featuring solder tab terminals, the thermostat is intended for fixed mounting arrangements, facilitating secure connections to printed circuit boards or wiring harnesses. The single-pole single-throw normally closed configuration simplifies wiring and enhances safety by maintaining circuit continuity until the preset temperature triggers an open state.

This thermostat is suited for overtemperature cut-out and thermal safety control in HVAC systems, industrial control panels, motors, transformers, and electronic assemblies. Its construction complies with RoHS standards, and it is manufactured in China.

Opens contact at 75°C to protect equipment from overheating. Rated for 10A contact current for moderate electrical loads. Accepts up to 250V AC for mains circuit compatibility. Automatic reset allows circuit restoration without manual reset.

Solder tab terminals facilitate PCB mounting and wiring harness assembly. Withstands maximum operating temperature of 186°C. SPST-NC contact configuration enables easy series wiring. Ideal for temperature safety in HVAC, industrial, and electronic applications.

This product is part of Honeywell's 2455R series thermostats, designed to provide dependable thermal protection in industrial and commercial environments. Suitable for preventative safety cut-outs and backup thermal safety, it supports system reliability and protects critical equipment.
