Munro SmartBox MPLC242 Series - Pump Start Relay - Munro Startbox - Reduced Incoming Amperage ( aka: The New Industry Standard ) This flexible, easy-to-install pump start relay provides “pilot-duty” operation for all electrically driven pump equipment and works with any reliable brand of 24v lawn controller – including 2-wire systems and those that provide less than .35 amps for pump start. Voltage specific – 110v or 220v – to match line voltage of the pump. Single unit eliminates the need for secondary transformers to be installed with decoders. Accepts a low amperage start signal from controller to provide all of the benefits of the standard StartBox, even though signal amperage is reduced.
