Rain Bird PSR110220 Dual Pole Pump Start Relays provide "pilot duty" operation for all types of electrically driven pump equipment with available 24 volt coil voltage. The PSR110220 is not recommended for two-wire irrigation systems. Please use Universal PSR and PSRP models with ice cube relay for better performance. 40 AMP UL listed relay Quick connect terminals with wire nuts Grounding provision Compatible with 24 VAC timed lawn controllers Compatible with 110 or 220 VAC 3/4 hp thru 5 hp* single phase pumps Grey “baked-on” powder coating, for long life in difficult environments UL Listed components, and backed by a limited two-year warranty Housed in compact NEMA 3R weather tight enclosures NOTE: Not recommended for 2-wire systems Additional features: Compatible with 110 or 220 VAC 3/4 hp thru 5 hp* single phase pumps * National electrical code (nec) states all motors will be thermally protected from excessive "amperage draw."
