ABB 1SDA0 R1 Switch Disconnect Rotary Handle Rod

ABB SACE 25436 Switch Disconnect Rotary Handle Rod, 1SDA0 R1, is an adjustable-depth rotary handle accessory that completes ABB’s rotary handle operating mechanism for fixed-plug-in MCCBs, enabling manual operation from the panel door. Designed for front-door actuation, it uses a 500 mm transmission rod to connect to XT1–XT3 fixed-plug-in breakers, with related variants supporting XT4 in the broader XT accessory family. The package includes a base for the adjustable-depth rotary handle and supports a padlock device, with UL/CSA listings for use in ABB SACE XT MCCB installations. This R1 revision sits within ABB’s 1SDA0 accessory lineup, and ABB catalog entries consistently reference 500 mm rods (RHE_S) designed for XT1–XT4 configurations, confirming cross-model compatibility across the XT series.
