Legacy Controls Essential Series LE-6003 Duplex Control Panel (120V/230V, 0-15FLA)

The Legacy Controls Essential Series LE-6003 is a reliable, heavy-duty duplex control panel designed for residential and light commercial septic systems, sewage lift stations, and effluent dosing applications that require two alternating submersible pumps.

Built for durability and simplicity, the LE-6003 provides true duplex alternation for even pump wear, automatic high-water alarm protection, and optional lag pump activation. It uses a proven four-float control strategy (Off, Lead On, optional Lag On, and High Water Alarm) and is ideal for new installations or as a direct replacement for older duplex panels.

This panel requires three float switches (sold separately). A fourth float switch can be added for full lag pump functionality during high-flow conditions.
