Rain Bird pump start relays work with a lawn controller’s start/stop command to facilitate the electrical path from the breaker box to the pump motor.
Rain Bird PSR Universal Pump Start Relays provide “pilot duty“ operation for all types of electrically driven pump equipment with available coil voltages of 24, 110 and 220 VAC.
* National electrical code (nec) states all motors will be thermally protected from excessive “amperage draw.” Most motors under 2 hp are supplied with thermal protection from the motor manufacturer. For motors over 2 hp, code-compliant Rain Bird PSRB pump protection is recommended.
NOTE: Circuit breakers are never classified as motor protection
NOTE: Check with your local health department for regulations and requirements for backflow prevention.
