MARS 19169 Potential Relay it is an OEM-level replacementThe MARS 19169 Potential Relay is a high performance motor starting relay designed for single phase HVACR systems, specifically for CSR (Capacitor Start, Capacitor Run) and CSIR (Capacitor Start, Induction Run) compressor configurations. This potential relay features a 332V continuous coil voltage, optimized to handle high back EMF (BEMF) across the start winding without premature failure. With a pick up voltage range of 180V to 193V and a drop out
