A hi-limit sensor helps protect a compatible heating system by responding to excessive temperature conditions, and this Invensys Appliance Controls version features a 1/4 inch diameter, 12 inch capillary, SPST design with screw terminals and a 25 amp rating using the 275-3287-00 reference. Hi-limit sensors are useful because they act as a critical safety component in systems where overheating can damage equipment or disrupt normal operation.

This part has practical value because the specific capillary length, diameter, switch format, and terminal style help preserve intended compatibility rather than relying on a near-match substitute. A properly selected Invensys hi-limit sensor contributes to more dependable temperature protection and more accurate restoration of the original heater-control setup.

This type of part is especially useful when the original sensor has failed, tripped unreliably, or no longer responds correctly to high-temperature conditions. That helps restore system safety with a direct and application-specific replacement.

Installed in the proper application, this hi-limit sensor helps support dependable over-temperature protection and stronger long-term heater reliability.
