EF460 Electronic Overload Relay (ABB Low-Voltage) provides electronic overload protection for AF400/AF460 motor starters, covering a 150–500 A current range. The EF460-500 variant offers adjustable trip class (commonly 10e, 20e, or 30e) to tailor protection to the motor, and supports automatic or manual reset. It includes a dedicated trip-indication output and a signaling contact (NO) for auxiliary control, along with temperature compensation to maintain accuracy across operating temperatures.
