Munro MPSR24 – 24V Pump Start Relay for Single-Phase Irrigation Pumps
The Munro MPSR24 pump start relay enables a standard 24V irrigation controller to switch single-phase pump motors up to 5 HP. Operating at 40 amps with 110/220V line voltage compatibility, it bridges the low-voltage irrigation control signal (0.36A) and the high-current pump circuit. Color-coded wiring and a compact 6"x6"x4" enclosure simplify installation in pump stations and control panels.
