Honeywell Bi-Metallic Thermostat, SPST Contact, 10A 250V AC, Closes at 110°C, Max 186°C Open/Close On Rise 2455RP-91000440

Honeywell 2455RP-91000440 is a bi-metallic thermostat designed for precise temperature control and safety functions in electrical and mechanical systems. It incorporates a reliable bimetallic element that actuates the SPST contact at a closing temperature of 110 °C, with a maximum tested operating temperature of 186 °C. This makes it suitable for demanding elevated-temperature environments where repeatable temperature actuation is critical.

The thermostat supports bracket mounting and automatic reset, providing seamless restoration of circuit continuity once cooled below the trip point. Its solder-tab terminals ensure robust, low-resistance connections necessary for industrial and aerospace applications.

The device carries a 10 A contact current rating at 250 V AC and features versatile switch functions, allowing it to open or close on temperature rise. This flexibility accommodates diverse control schemes and thermal management requirements.

Certified to stringent standards including MIL-STD-202, VDE, CSA, UL, Mil-PRF-24236, and space-qualified credentials recognized by NASA, this thermostat meets demanding regulatory and performance criteria. Note that the contacts are not silver plated and are unsuitable for low current DC applications.

Applications include thermal protection on aerospace avionics racks, temperature monitoring in industrial control panels, and over-temperature shut-off in electrical assemblies. Additionally, it is suitable for thermal management in space-qualified electronic modules.

Equipped with a bimetallic sensing element for temperature actuation. SPST contact configuration rated for 10 A at 250 V AC. Automatic reset for restoring circuit continuity post temperature drop. Bracket mount for easy installation.

Switch functions: open or close on rise to fit control needs. Compliant with MIL-STD-202, VDE, CSA, UL, NASA, and Mil-PRF-24236 standards. Contact terminals feature solder tabs for low-resistance secure connections.
