Honeywell 2455R Series Thermostat, 85°C Closing Temperature, 10A Contact Current - 2455R--00820191
This thermostat is a Compact temperature-operated switch designed for commercial electrical and mechanical systems where automatic thermal control is required. It provides a simple open-or-close response as temperatures rise, and is suitable for integration via PCB or panel mounting using a discrete through-hole footprint.
Features and Benefits:
• SPST contact rated 10 A for straightforward circuit switching
• Closes at 85°C to protect against moderate overheating
• Automatic reset restores operation without manual intervention
• Quick-connect terminals for Rapid field wiring
• Operates up to 150°C for high-temperature exposure
• Complies with multiple approvals for stringent environments
• Closes at 85°C to protect against moderate overheating

What contact arrangement does it provide for system designers?
It uses a single-pole single-throw contact configuration that changes state on temperature rise, simplifying incorporation into single-circuit protection schemes.
How does the device behave after an overtemperature event?
The device resets automatically once the ambient temperature falls below its threshold, allowing systems to resume operation without manual reset.
What environmental temperature range can it tolerate during storage or non-operational exposure?
It is specified for use where ambient conditions do not fall below 0°C, ensuring reliable performance in commonly encountered industrial environments.
What approvals support its use in regulated applications?
It holds qualifications from bodies including VDE, CSA and UL as well as meeting MIL‑STD‑202 and NASA-related criteria for certain demanding installations.
