• 3 Ph Line Monitor - Service

The Bard S8201-126 is an OEM 3 phase line monitor used in Bard wall-mounted HVAC equipment to help protect the unit from damaging power conditions such as phase loss, phase reversal, and improper three phase supply. This control safeguards critical components by monitoring the incoming power and allowing proper operation only when the electrical phases are correct, which helps prevent nuisance trips and costly compressor or motor damage. It is commonly referenced in Bard parts listings as a phase monitor and may be superseded by newer Bard service part numbers, so confirm the exact replacement specified for your unit model and serial before ordering.
