| FFF Compatibility | The mounting interface, 22.3mm cutout, and contact block attachment are identical since it belongs to the same Siemens SIRIUS ACT series.Features the same 40mm red mushroom head and physical dimensions, but uses a metal bezel instead of plastic.Provides the identical rotate-to-unlatch, positive-latching emergency-stop function. | Requires Schneider Electric Harmony XB5 series contact blocks and mounting collars; not compatible with Siemens accessories.Sits in the same standard 22mm round cutout with a 40mm red mushroom head.Provides the identical rotate-to-unlatch latching emergency stop behavior. | ||
 AI Summary | 3SU1000-1HB20-0AA0 by Siemens: Configurable Switch Body E-Stop, Round Non-Illuminated. | This is the direct premium sibling from the same SIRIUS ACT series, utilizing a metal collar rather than a plastic one. It acts as a perfect physical and electrical drop-in replacement, supporting the exact same contact blocks and holders without any design changes.
| This is a prominent second-source industry-standard equivalent from the Schneider Harmony XB5 series. It offers a plastic collar and rotate-to-unlatch mechanism, but requires transitioning to Schneider's proprietary contact block and collar system behind the panel.
