Honeywell 2455RM Series Thermostat, 250V AC Contact Voltage, 10A Contact Current - 2455RM-90820471


This thermostat is a commercial temperature cut-off switch designed to interrupt circuits when temperatures rise. It operates as a single-pole single-throw device for control tasks in industrial and HVAC environments, mounted via a bracket and intended for manual reset after actuation. The unit is suitable for systems requiring a straightforward open-on-rise safety function and solder-tab electrical connections.

Features and Benefits:


• Opens circuit on temperature rise for overheat protection
• Manual reset function enables controlled system restart
• Rated for 250VAC operation to handle mains voltages
• 10A contact capacity supports common load currents
• Solder-tab terminals allow secure PCB or wiring attachment
• Withstands up to 150°C for high-temperature applications

Applications


• Suitable for commercial HVAC limit to prevent overheating
• Used for thermal protection in industrial control panels
• Ideal for electrical heating assemblies requiring manual reset
• Can be used for automation equipment temperature cut-off tasks

What contact arrangement does it use and how does that affect wiring?


It uses a single-pole single-throw contact, providing a simple series break suitable for inserting into control or safety loops where a single switching element is required.

How should the device be mounted in equipment?


The bracket mount permits fixed attachment to frames or panels

secure mechanical mounting ensures reliable temperature sensing and prevents movement that could affect trips.

What reset action is required after an actuation?


Following activation, a manual intervention resets the mechanism, allowing inspection and deliberate restart rather than automatic reclosure.

Which environments are unsuitable based on temperature limits?


It should not be used in locations that routinely fall below 0°C or exceed 150°C, as those conditions lie outside the specified operating range.

What approvals or material restrictions are noted?


The component complies with RoHS requirements, indicating restriction of certain hazardous substances in its construction.
