Liberty's 5050V is a 5050-Series duplex control and alarm that alternates two 120V pumps (1 HP, 15A each) after every cycle to equalize wear and extend pump life — plug-in ready, no hard wiring required, running one pump at a time. NEMA 1 indoor thermoplastic enclosure (6"x6"x4") with two angled NEMA 5-15 receptacles that accept standard or right-angle plugs, a factory-installed 10' power cord, green power-on and pump-run indicators, an audible/visual high-water alarm with an externally mounted Normal/Silence switch, and stainless steel brackets for mounting the float switches to the discharge pipe. Ships with factory-wired vertical-style float switches on 10' cords. UL listed.
