Honeywell 2455R Series Thermostat, 25°C Closing Temperature, 10A Contact Current - 2455R--00820196


This thermostat is a commercial thermal switch designed to open or close a circuit in response to rising temperature. It operates as a single-pole single-throw device with an automatic reset mechanism suited to industrial and aerospace environments. The unit is bracket-mounted and intended for integration where a simple temperature-responsive control is required.

Features and Benefits:


• Opens or closes on temperature rise ensuring clear thermal action
• Rated for 10A at 250V AC for robust current handling
• Closing set point at 25°C for predictable trip behaviour
• Operates from 0°C to 150°C for wide thermal range capability
• Solder tab terminals for secure electrical connections
• Meets multiple military and safety standards for demanding use

Applications


• Suitable for temperature monitoring in control panels and cabinets
• Ideal for thermal protection in industrial heating systems
• Used with avionics modules requiring qualified thermal switching
• Can be used for environmental test rigs and space hardware support
• Suitable for retrofit in existing bracket-mounted assemblies

How is the device mounted and connected electrically?


It is designed for bracket mounting and uses solder tab terminals for direct wiring or soldered leads.

What happens after the switch actuates at its set temperature?


The unit resets automatically when the temperature falls below the release threshold, restoring the circuit without manual intervention.

Are there approvals relevant to high-reliability sectors?


The switch carries approvals and qualifications aligned with military, space and recognised safety organisations, supporting use in regulated projects.

What switch behaviour should engineers expect under thermal stress?


It functions as an SPST thermal actuator that changes state on rise in temperature, suitable for straightforward open-or-close control schemes.
