The ABB EF45-30 is a self-supplied electronic overload relay designed for reliable and fast motor protection against overload and phase failure. It offers the ease of use of a thermal overload relay with enhanced features like a wide setting range, high accuracy, and an extended operational temperature range. Selectable trip classes (10E, 20E, 30E), temperature compensation, and integrated trip (NC) and signal (NO) contacts provide comprehensive protection. Features include automatic or manual reset selection, a trip-free mechanism, and STOP/Test functions with trip indication. Designed for direct connection to contactors, with optional mounting kits available. The EF45-30 also boasts ATEX and IECEx certification..The EF45-30 is an electronic overload relay with a self-supplied design, eliminating the need for external power. It provides motor protection with a setting range of 9.0 to 30A and is compatible with E/EF series contactors. The relay offers a rated insulation voltage of 690V and an operational voltage of 600V AC/DC for auxiliary circuits and 690V AC for main circuits. It features 3 poles and screw terminals for mounting. The relay includes a trip contact (NC) and a signal contact (NO), with selectable automatic or manual reset. It is designed for direct mounting on contactors and has a trip indication feature. The device operates within an ambient air temperature range of -25 to +70 degrees Celsius.
