• Limit L150-30/3" Black/Yellow

Bard 8402-135 is an OEM high temperature limit switch used in Bard wall mounted HVAC equipment to protect the unit from overheating conditions. This control opens on a rise in temperature to shut down the heat circuit until temperatures return to a safe range, helping prevent heat exchanger damage and nuisance trips caused by restricted airflow, blower issues, or blocked filters. The Limit L150-30/3 specification indicates a 150 degree F cutout style limit with a 3 inch sensing element commonly used on Bard gas/electric wall mount applications, making it a dependable direct fit replacement when you confirm the part number and switch style in your unit wiring diagram or parts list.
