Bard 8401-043 - Auxiliary normally open contact

Bard part 8401-043 is an OEM auxiliary normally open contact used with Bard HVAC electrical control assemblies to provide a positive status or interlock signal when a primary device is energized. This type of aux contact is commonly used for control logic, monitoring, or staging circuits where you need an extra set of dry contacts without changing the main power wiring. Replacing a worn or damaged auxiliary contact helps restore dependable call-for-operation feedback and prevents nuisance control issues caused by intermittent contact closure. Verify the exact unit model and the controlled device this auxiliary contact mounts to so the connection style and ratings match your Bard factory configuration.
