Little Giant Duplex Alarm and Pump Control System, 240V 1 Phase, 20 A - 513258

The Little Giant 513258 is a duplex alarm and pump control panel for two-pump water or sewage systems in homes and commercial buildings. It runs on 240V single-phase power, rated 20 A, and uses three floats to manage pump on, pump off and high-water alarm.

The pre-assembled, non-corrosive enclosure is rated for indoor or outdoor use and carries a large red alarm beacon. A test/normal/silence switch on the outside lets the 83-85 dB buzzer be muted or the buzzer and light be checked. Inside are two heavy-duty motor contactors, a printed circuit board controller and a 25 watt maximum light bulb.

Two HOA switches select hand, off or automatic for each pump, and a separate control switch shuts off power to the float circuit; all sit inside the panel, out of reach of unauthorized hands, and can be turned off during service. Green run lights on the board show pump status, and a terminal strip with wiring diagram simplifies hookup. Each float has a 20 ft cord.
