Honeywell 2455R Series Thermostat, 105°C Closing Temperature, SPST Contact Configuration - 2455R--00820715


This thermostat is a commercial-grade temperature switch designed to monitor and control temperature in industrial and automation systems. It operates by opening or closing a circuit as temperature rises, with an automatic return to service after conditions normalise. The unit is intended for bracket mounting and connects via quick-connect terminals to integrate with existing electrical assemblies.

Features and Benefits:


• Closing action at 105°C provides precise trip point control
• SPST contact supports straightforward single-circuit switching
• 15A rating enables handling of moderate mains loads
• 250V AC contact voltage suits standard supply networks
• Automatic reset eliminates manual intervention after trip
• Rated to 150°C maximum for elevated-temperature environments

Applications


• Suitable for thermal protection of control panels and enclosures
• Ideal for safety cut-out on industrial heaters and ovens
• Used with motor control systems requiring temperature monitoring
• Can be used for protecting transformers and switchgear assemblies

What contact arrangement does it offer for circuit design?


It uses a single-pole single-throw contact configuration, permitting a simple on/off switching function within control circuits.

How is the device mounted and connected in a panel?


The unit is designed for bracket mounting and uses quick-connect terminals for Rapid installation and replacement.

What standards and approvals support its use in demanding environments?


It holds multiple approvals including NASA certification, MIL‑PRF‑24236, MIL‑STD‑202, UL, CSA and VDE indicating suitability for stringent operational conditions.

How does the device behave after a temperature-triggered operation?


The mechanism resets automatically once temperature falls below the actuation threshold, restoring continuity without manual resetting.
