About This Item

The Pentair Relay Kit, 20 Amp (520106) is the OEM replacement relay assembly for Pentair IntelliCenter and EasyTouch pool and spa automation control systems rated for 3 HP loads.

IMPORTANT: LICENSED PROFESSIONAL INSTALLATION REQUIRED
Electrical control components must be installed or replaced by a qualified electrician or certified pool technician. This relay assembly is a mains-voltage component inside a live load center or control panel. De-energize the system completely before servicing.

This relay kit is the switching component that controls 3 HP-rated equipment circuits — such as pumps and auxiliary loads — within compatible Pentair automation load centers and control boards. A failed relay can result in circuits that fail to switch on or off, loss of equipment control, or intermittent operation that appears as a programming or communication fault. Replacing the relay restores proper circuit switching function to the automation system.

Poolaroo Pro Tip

Before ordering, open your load center or control panel door and locate the relay on the PCB. The part number is printed directly on the relay body — confirm it matches 520106 before purchase. Relay failure typically presents as a circuit that will not respond to automation commands despite correct programming, or a circuit that stays energized or de-energized regardless of schedule. Always have a licensed electrician or certified pool technician perform the replacement — this component is mounted inside a live load center with mains voltage present.
