A Hubbell Heaters CAP-MR-186 Hi-Limit Switch monitors temperature levels closely, interrupting power when heat within the assembly reaches unsafe levels.
The hi-limit switch monitors temperature conditions and interrupts power when the heating and cooling equipment reaches an unsafe limit, protecting components from overheating and damage. Its surface-mount design and 240V, 20/2.9A rating matter because they provide secure installation and proper electrical compatibility for dependable response within the HVAC system.
The hi-limit switch may need to be replaced if the heating and cooling unit shuts down unexpectedly, cycles irregularly or could fail to cut power when overheating occurs. Common indicators include visible wear or heat damage at the switch and environmental signs may include exposure to excessive moisture, dust buildup or corrosion that can affect reliable operation.
