Honeywell 2455R Series Thermostat, 5°C Closing Temperature, 10A Contact Current - 2455R--90820459


This thermostat is a commercial-grade temperature control device designed for industrial equipment operating across a broad thermal range. It functions as a single-pole single-throw switch that changes state as temperature rises, available with either automatic or manual reset, and is mounted using a bracket for secure installation in demanding settings. The design includes solder-tab terminals and is suitable where a clearly defined closing temperature and robust electrical switching are required.

Features and Benefits:


• Operates between 0°C and 150°C to cover wide thermal scenarios
• Switches at 5°C closing temperature for predictable activation
• SPST contact configuration for simple on/off control
• Rated 10A at 250V AC to handle moderate power loads
• Solder-tab terminals for reliable PCB or wiring connections
• Automatic and manual reset options for flexible responses

Applications


• Suitable for temperature protection in industrial heaters
• Ideal for monitoring equipment in high-temperature processes
• Used with control panels requiring bracket-mounted components
• Can be used for thermal safety in avionics test rigs
• Suitable for integration into ruggedised instrumentation assemblies

What contact arrangement does it use for switching?


It employs a single-pole single-throw contact that opens or closes on temperature rise.

How is the device secured within installations?


It is fitted for bracket mounting to ensure a stable, fixed position on frames or panels.

What terminal format is provided for electrical connection?


Connections are presented as solder tabs suitable for direct soldering to wiring or board terminations.

Are there options for how the device resets after actuation?


Yes, it is available with either an automatic reset mechanism or a manual reset option to suit different control philosophies.
