Honeywell 3455RC Series Thermostat, 85°C Closing Temperature, 250V AC Contact AC Voltage - 3455RC 01000235

This thermostat provides automatic temperature control for commercial and industrial systems by opening its contact as temperature rises. Designed for bracket or Terminal installation, it operates in applications where a reliable open-on-rise switching action is required and supports AC control circuits up to specified voltage ratings.

Features and Benefits:

• Opens on temperature rise offering clear trip behaviour
• SPST contact configuration simplifies control wiring
• Rated for 250V AC compatibility with common supply systems
• Automatic reset avoids manual intervention after cool-down
• Operates up to85°C for high-temperature protection
• Bracket and Terminal mount options enable flexible installation

Applications

• Suitable for overtemperature protection in control panels
• Ideal for HVAC safety cut-outs in commercial systems
• Used for thermal monitoring in industrial equipment racks
• Can be used for temperature-triggered shutdowns of motors
• Used with electrical assemblies requiring a single-pole switch

What electrical switching arrangement does it use?

It employs a single-pole single-throw contact that opens when the monitored temperature rises, allowing straightforward integration into Basic control loops.

How does the device behave after it trips?

The mechanism resets automatically once the temperature falls below the release point, enabling cyclical protection without manual reset.

Which approvals indicate suitability for demanding operational environments?

It complies with military and recognised safety standards including MIL-STD-202, Mil-PRF-24236, VDE, CSA and UL, and holds NASA certification for specialised applications.

How is the unit mounted and connected electrically?

The design provides both bracket mounting and Terminal connections, permitting secure mechanical fixing and direct electrical termination in tight installations.
