MARS 19171 Potential Relay 420V Coil Voltage 171

The MARS 19171 Potential Relay stands as an HVAC system relay that operates on 420V coil voltage and supports 35A of current. The tab-mounted Potential Relay functions in single-phase motors of air conditioning and refrigeration systems to switch the start capacitor out of the circuit at the correct motor speed. The relay functions optimally with compressors found in residential and commercial HVAC system units to improve motor performance while reducing Damage and enhancing total energy efficiency. Reliable capacitor systems prevent overheating and improve equipment longevity. The equipment features a small and sturdy construction which enables convenient installation across heat pumps, central air conditioners, and other HVAC systems.
