Rain Bird PSR110220
Dual Pole Pump Start Relay

Rain Bird Dual Pole Pump Start Relays

The Dual Pole Pump Start Relay offers 110 or 220 voltage in one unit giving you flexibility for your pump installations.  Rain Bird pump start relays work with the irrigation controller’s start/stop command to facilitate the electrical path from the breaker box to the pump motor.

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 models with ice cube relay for better performance.
