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.

Features

  • 40 AMP certified 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 as “Enclosed Industrial Control Panels” and backed by a limited two-year warranty
  • Housed in compact NEMA 3R weather tight enclosures

* 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.
