ABB CR324DXJS is a size-2, three-pole solid-state overload relay designed to accompany NEMA size 2 motor starters. It provides electronic overload protection for three‑phase motors in a panel‑mount package, with a current range of 25–50 A. As part of the CR324X family, it is commonly used in 3‑phase AC circuits up to 600 V AC and is mounted in control panels to protect motors from overload by monitoring motor current and tripping when the preset range is exceeded.
