Honeywell 2455R Series Thermostat, 75°C Closing Temperature, 10A Contact Current - 2455RP-91000437
This bi-metallic thermostat provides temperature-responsive contact control for industrial and HVAC systems, operating as a normally closed single-pole switch that opens at a preset threshold. It is intended for installations where automatic thermal cut-out and passive reset are required, and it is suitable for environments that demand solder-tab terminations for secure electrical connections.
Features and Benefits:
• Opens contact at75°C to prevent overheating and protect equipment
• Rated for10A current to handle moderate load switching
• Accepts up to250V AC enabling use on mains AC circuits
• Automatic reset behaviour restores circuit when temperature falls
• Withstands up to186°C maximum operating temperature for high-stress events
• Solder tab terminals simplify PCB or wiring-harness assembly
• Rated for10A current to handle moderate load switching
• Accepts up to250V AC enabling use on mains AC circuits
• Automatic reset behaviour restores circuit when temperature falls
• Withstands up to186°C maximum operating temperature for high-stress events
• Solder tab terminals simplify PCB or wiring-harness assembly
Applications
• Suitable for temperature safety control in HVAC systems
• Ideal for thermal protection of industrial control panels
• Used for overtemperature cut-out in motors and transformers
• Can be used for backup thermal safety in electronic assemblies

What contact arrangement does it use and how does that affect wiring?
It uses a single-pole single-throw normally closed contact, so the circuit is completed until the device opens at its trip point, enabling straightforward series wiring for load interruption.
How does reset behaviour influence system restart after a trip?
The thermostat returns to the closed state automatically as temperatures fall below the release point, allowing systems to resume without manual intervention once safe conditions are restored.
What Terminal type should installers expect and how does that impact mounting?
Termination is via solder tabs, which require soldering to a PCB or secure wiring lugs and are suitable for fixed installations rather than frequent connector cycles.
What thermal extremes can the device tolerate during abnormal conditions?
It can endure ambient or transient temperatures up to186°C without functional failure, offering resilience during severe thermal excursions.
