Honeywell 2455R Series Thermostat, 100°C Closing Temperature, 250V Contact AC Voltage - 2455R--00820711
This snap-action thermostat is a temperature-operated safety and control device designed for industrial and electronic systems. It monitors thermal conditions and initiates an instantaneous change of contact state as temperatures rise, providing straightforward over-temperature interruption within equipment assemblies. The product is suited to panel or component mounting where a Compact thermal cut-out with bracket or Terminal attachment is required.
Features and Benefits:
• Opens contact on temperature rise for immediate circuit interruption
• SPST contact arrangement for simple single-circuit switching
• Rated for 250VAC ensuring compatibility with common mains systems
• One-shot reset prevents unintended reclosure after activation
• Operates reliably up to 150°C for high-temperature environments
• Quick-connect terminals enable fast installation and replacement
• SPST contact arrangement for simple single-circuit switching
• Rated for 250VAC ensuring compatibility with common mains systems
• One-shot reset prevents unintended reclosure after activation
• Operates reliably up to 150°C for high-temperature environments
• Quick-connect terminals enable fast installation and replacement
Applications
• Suitable for thermal protection in industrial heaters and ovens
• Ideal for safety cut-outs in motor and pump assemblies
• Used for temperature control in electrical distribution panels
• Can be used for over-temperature protection in HVAC components
• Suitable for retrofit safety upgrades in factory automation systems
