ABB CR324CXGS Solid State Overload Relay

The ABB CR324CXGS is a solid-state overload relay that provides electronic motor protection for small-to-medium AC motors in NEMA Size 0 and 1 configurations, designed to mount with ABB CR306B/C motor starters in control panels and motor-control centers. It features a continuous current range of 6.5 to 13.5 amps, accepts 75°C copper conductors in sizes 14 to 8 AWG, and supports a maximum fuse size of 50 amps and a maximum breaker rating of 50 amps, enabling coordinated protection with the starter. As part of ABB's CR324X family, the CR324CXGS offers an electronic alternative to older bimetallic CR324 relays, with current sensing and overload trip behavior suited to reliable motor safeguarding. It is intended for use with ABB CR306B/C contactors and is commonly applied in conveyor, pump, and fan duty where compact protection with the CR306B/C is required. This model, like other CR324X devices, simplifies parts replacement and maintenance within ABB-based control systems while ensuring consistent trip characteristics across the CR324 line.
