Honeywell Commercial Thermostat SPST, Automatic Reset, 5°C Closing, 250V AC, 10A, Bracket Mount 2455R--90820459

Honeywell 2455R--90820459 Commercial Thermostat is a robust temperature sensing and switching solution engineered for industrial, laboratory, and commercial electrical systems. This thermostat is designed to close contacts at 5°C with operation supported across a wide - from 0°C up to 150°C - making it ideal for equipment requiring precise temperature cutoff and protection. The reliable SPST (Single Pole Single Throw) contact architecture provides direct on/off control for heaters, fans, or alarms, ensuring operational safety and efficiency in challenging thermal environments.

This model features an automatic reset mechanism - once the sensed temperature returns to the safe range, the control circuit is automatically restored, eliminating the need for manual intervention. Its rugged bracket mount design ensures easy and secure installation on panels or frames, while solder tab terminals enable a dependable electrical connection to wiring or PCB terminations commonly used in industrial assemblies.

Closes at a defined 5°C temperature, supporting controlled switching for thermal events. Wide operating range up to 150°C enables usage with heating, ventilation, and safety interlock circuits. SPST configuration simplifies integration into safety shutoff or control circuits.

Rated for 250V AC up to 10A, fitting a variety of resistive or inductive load devices. Automatic reset design streamlines processes and helps reduce downtime. Compliant with major industrial and safety standards (UL, VDE, CSA, MIL-STD-202, NASA certified) for global compatibility and reliability.

This Honeywell commercial thermostat is widely used in control panels, automation assemblies, process monitoring, temperature protection for industrial heaters, and equipment safety systems. Its robust design also makes it suitable for use in test rigs, ruggedized instruments, and avionics equipment where dependable thermal cutoff is essential.

Whether used in manufacturing, laboratory, aerospace, or utility operations, this automatic reset thermostat delivers consistent and repeatable thermal management. For more advanced control needs or multi-zone systems, explore further models within the EnvMart Thermostatic Switches range.
