The Bard 8402-010 is an OEM limit control used to protect Bard wall mount HVAC and packaged equipment from unsafe temperature rise by opening the electrical circuit at its setpoint and allowing the system to shut down before components overheat. Rated 150F open and 125F close, this high reliability safety switch helps maintain proper heater and airflow safety operation and is commonly used anywhere Bard specifies a high limit in the heat section or related temperature protection circuit. Confirm the exact part number and temperature ratings against your unit model and wiring diagram to ensure correct fit and safe operation.
