Honeywell Thermostat, 135°C Closing Temperature, 10A Contact Current - 2455RP-91000441
This thermostat is a commercial-grade temperature control device designed to open or close electrical contacts in response to temperature changes. It operates automatically to reset after a trip and is intended for use where controlled switching at elevated temperatures is required. The unit is suited to bracket mounting and connects via solder tab terminals for direct electrical integration.
Features and Benefits:
• Opens on temperature rise to protect downstream components
• Closes on temperature rise for control or signalling functions
• Single-pole single-throw contact rated 10A for moderate loads
• Accepts up to 250V AC for compatibility with common AC supplies
• Operates from 0–186°C to handle wide thermal ranges
• Automatic reset removes need for manual intervention
• Closes on temperature rise for control or signalling functions
• Single-pole single-throw contact rated 10A for moderate loads
• Accepts up to 250V AC for compatibility with common AC supplies
• Operates from 0–186°C to handle wide thermal ranges
• Automatic reset removes need for manual intervention
Applications
• Suitable for thermal protection in industrial heaters
• Ideal for temperature signalling in automation panels
• Used with control circuits requiring SPST switching
• Can be used for over-temperature sensing in electrical enclosures
• Suitable for avionics test rigs requiring certified components

What Terminal style does it use for mounting on wiring assemblies?
It employs solder tab terminals designed for soldered connections to wires or PCB pads.
How does the device behave after it trips due to heat?
The mechanism resets automatically once temperature falls below the actuation threshold, restoring the contact state without manual reset.
What switching configurations are available for different control needs?
The internal contact is SPST and configured to open on rise and also provides a close-on-rise function depending on circuit wiring.
What approvals indicate suitability for demanding technical applications?
It carries recognised approvals including UL, CSA and VDE, and has certification used in aerospace contexts.
Note
The contacts are NOT silver plated and are unsuitable for use with low current dc applications
