MARS 19008 Relay Els PW 17895 this liquid line sight glassThe MARS 19008 Relay is an industry standard 336V 69 Potential Relay engineered for heavy duty single phase capacitor start capacitor run motors where high starting torque is essential. This motor starting component operates on the back EMF principle, utilizing a high resistance coil to precisely disconnect the start capacitor once the compressor reaches approximately 75% of its operating speed. Rated at 35 Amps with a continuous coil voltage of 336V,
