Bard 8402-174 - Limit Control Switch

Bard part 8402-174 is an OEM two pole limit control labeled L180-7.0, used as a safety temperature cutoff in Bard wall mounted HVAC equipment to help protect the unit from overheating by opening the circuit when the limit is reached. This switch is commonly found in the heat section or air handler safety chain and is a direct fit replacement intended to restore original Bard safety operation and reliable cycling after a failed or nuisance tripping limit. Verify your model and serial number compatibility and match the exact limit rating and wiring configuration before installation to ensure proper protection and correct system performance.
