Honeywell 2455R Series Thermostat, 135°C Closing Temperature, 10A Contact Current - 2455R--00820235
This thermostat is a Compact commercial thermal switch designed to operate as a temperature‑actuated control in electrical and mechanical systems. It monitors temperature and changes contact state on rising temperature to protect circuits or trigger downstream control logic in non‑hazardous environments.
Features and Benefits:
• Opens or closes on temperature rise to control heating processes
• Automatic reset restores circuit continuity after cooling
• SPST contact supports single‑circuit switching at rated load
• 10 A contact current enables moderate‑power switching applications
• 250V AC contact rating suitable for standard mains circuits
• Through‑hole mount with solder tab terminals for PCB assembly
• Automatic reset restores circuit continuity after cooling
• SPST contact supports single‑circuit switching at rated load
• 10 A contact current enables moderate‑power switching applications
• 250V AC contact rating suitable for standard mains circuits
• Through‑hole mount with solder tab terminals for PCB assembly
Applications
• Suitable for thermal protection in industrial control panels
• Ideal for temperature monitoring in HVAC equipment
• Used with motors to prevent overheating during prolonged duty
• Can be used for temperature safety in commercial appliances
• Suitable for integration into automated test rigs requiring thermal cutover

What temperature range can it reliably operate within?
It functions between 0 °C minimum ambient and 150 °C maximum operating temperature, with the switching point set to trigger at 135 °C.
How is the unit reset after it actuates?
The device returns to its original contact state automatically once the temperature falls below the specified threshold.
Which mounting and electrical connection methods are provided?
It mounts via a through‑hole configuration and uses solder tab terminals for direct PCB or wiring connection.
Is this suitable for use in explosive atmospheres?
It has no hazardous‑area certification and is intended for use in non‑hazardous locations only.
