SACE Emax 2 Cradle/Fixed Parts Design Optimization Notice

This document announces a design optimization for ABB SACE Emax 2 withdrawable cradle/fixed parts, effective April 30, 2025, where certain auxiliary contact blocks inside the terminal box will no longer be provided as standard. It details the impact on ground fault protection, residual current, Modified Differential Ground Fault Protection (MDGF), and Zone Selective Interlocking (ZSI) applications, specifying that these contact blocks must now be ordered separately as sensor kits or loose kits.
