When a system requires the use of a booster pump or pulls water directly from a creek or pond, it’s imperative to include a relay that can be counted on to activate the pump each and every time. Hunter’s Pump Start Relay (PSR) has been created to provide that reliability–as well as a lockable NEMA rated enclosure–at an economical price. Available in a choice of three models to accommodate a variety of power sources and landscape needs, the PSR is fully compatible with all standard 24VAC controllers. It’s also designed with user-friendliness in mind. Flying wire leads allow for effortless 24V connections. Plus a wide array of "knockouts" make wiring easy and accommodating to most mounting specifications.
