- Low Press Swt. Auto Reset CO 27 / CI 52
Bard part 8406-063 is an OEM low pressure safety switch used on Bard wall-mounted air conditioners and related packaged equipment to protect the refrigeration circuit when suction pressure drops too low, such as during a loss of charge, airflow issues, or coil freeze conditions. This switch opens the safety circuit at a 27 PSI cut-out point to shut the system down and, because it is auto reset, it will allow operation to resume once pressure returns to a normal range, helping prevent nuisance lockouts while still guarding the compressor from damaging low-pressure operation. Use the correct Bard part number to ensure proper setpoint, wiring compatibility, and fitment for your specific unit and refer to the unit wiring diagram or service manual to confirm the exact safety circuit application before ordering.
