Honeywell Technologies Bi-Metallic Thermostat, Closes at 95°C, Maximum 186°C Open On Rise, SPST Contact 2455RP-91000439

Honeywell Technologies 2455RP-91000439 Bi-Metallic Thermostat is a reliable thermal switch designed for commercial, aerospace, and industrial applications requiring automatic temperature-triggered switching.

This thermostat closes at 95°C and can withstand maximum opening temperatures up to +186°C. It employs a single-pole single-throw (SPST) contact arrangement, enabling it to open or close circuits on temperature rise based on wiring configuration.

The device mounts securely on brackets and connects electrically using solder tab terminals, ensuring durable mechanical and electrical connections within assemblies. Its automatic reset functionality restores normal operation after the temperature falls below the trip point, reducing downtime and maintenance needs.

With a contact rating supporting up to 250V AC and 10A current, it satisfies demanding electrical requirements for control and protective functions. It carries multiple certifications including VDE, UL, CSA, NASA, and military standards like Mil-PRF-24236 and MIL-STD-202, signifying its suitability for regulated and high-reliability sectors.

This thermostat is ideal for thermal protection within industrial automation panels, aerospace hardware requiring space-qualified components, commercial HVAC temperature monitoring, and safety cut-out in mechanical drive enclosures.
