MARS 19166 Potential Relay Compact Footprint: Designed to minimizeThe MARS 19166 Potential Relay is a specialized HVAC compressor start relay designed for demanding capacitor start induction run (CSIR) and capacitor start capacitor run (CSCR) motor applications. Operating at a 395V continuous coil voltage with a robust 35 amp contact rating, this Type 166 potential relay accurately monitors back EMF to precisely manage start capacitor dropout. Engineered as a universal replacement relay, it features a non positional
