Schneider Electric 9065AK Three Phase Overload Relay

Schneider Electric's 9065AK is a three‑pole overload relay in the Square D Motor Logic Class 9065 family, designed to guard three‑phase motors in industrial control panels. It interrupts motor current when the electrical load exceeds safe limits, helping prevent winding damage from overheating and overcurrent conditions. The 9065 family includes both melting‑alloy and solid‑state variants, offering flexible protection approaches for motors in pumps, fans, conveyors, and other equipment, and it is designed to work with compatible motor starters and contactors in standard control‑panel configurations. Depending on the exact model, it provides protection for 3‑phase operation across a range of current ratings and voltages, with many variants rated for standard three‑phase voltages up to 600 VAC. This relay is intended for integration into existing starter assemblies, enabling straightforward replacement of older protection devices in industrial motor circuits.
