Honeywell 2455R Series Thermostat, 75°C Closing Temperature, 15A Contact Current - 2455R--00820712
This thermostat is a commercial temperature control switch designed to open or close circuits as ambient temperature rises. It is intended for bracket-mounted installation in industrial and commercial HVAC and equipment environments, operating across a wide thermal range while providing single-pole single-throw switching for straightforward control tasks.
Features and Benefits:
• Opens or closes on temperature rise to simplify control logic
• Automatic reset for hands-free return to normal operation
• Rated contact current 15A for moderate power switching
• Contact AC voltage rating 250V for common supply compatibility
• Operates from 0–150°C to handle varied process conditions
• Quick connect terminals for fast maintenance and wiring
• Automatic reset for hands-free return to normal operation
• Rated contact current 15A for moderate power switching
• Contact AC voltage rating 250V for common supply compatibility
• Operates from 0–150°C to handle varied process conditions
• Quick connect terminals for fast maintenance and wiring
Applications
• Suitable for temperature control in commercial HVAC systems
• Ideal for monitoring and switching in electrical panels
• Used with industrial heaters and fans for overtemperature protection
• Can be used for equipment safety cut-off in mechanical systems
• Suitable for installations requiring bracket-mounted sensors

What contact arrangement does it use for control circuits?
It employs a single-pole single-throw contact configuration to provide a straightforward open-or-close switching action for one circuit.
How does the device behave after it trips due to heat?
The mechanism resets automatically when the ambient temperature falls below the release threshold, restoring the contact state without manual intervention.
Which approvals support installation in regulated environments?
It holds UL, CSA and VDE approvals and carries a NASA certification for specific validated applications.
What mounting and termination methods are provided for field installation?
The unit mounts via a bracket and uses quick connect terminals to enable Rapid wiring and replacement.
What environmental temperature limits define its operating envelope?
The device is specified to function within a minimum of 0°C and a maximum of 150°C.
