| FFF Compatibility | Legacy 3SB3 contact blocks and holders are not directly compatible with the new 3SU1 series; a new SIRIUS ACT mounting holder (3SU1500-0AA10-0AA0) is required.Fits standard 22 mm round installation cutout and retains the 40 mm red mushroom profile.Provides identical positive latching and rotate-to-unlatch emergency stop safety performance. | Requires Schneider ZB5AZ101 mounting collar and Harmony XB5 contact blocks instead of Siemens hardware.Installs into standard 22 mm panel cutouts with matching 40 mm red mushroom aesthetics.Provides identical emergency stop, stay-put latching, and turn-to-release functionality. | ||
 AI Summary | 3SB30001HA20 by Siemens: Emergency Stop Switch Panel Mount, Front. | This is the official direct successor series (SIRIUS ACT) recommended by Siemens to replace the obsolete 3SB3 series. It requires purchasing a new plastic holder (3SU1500-0AA10-0AA0) and compatible 3SU1 contact modules. This active, highly reliable line offers improved environmental sealing up to IP69K.
| The Harmony XB5 series from Schneider Electric is a premium second-source equivalent with an active lifecycle. It fits the same 22 mm cutout and functions identically as a latching, twist-to-release 40 mm emergency stop. Note that this modular solution requires a ZB5AZ101 collar and compatible Harmony contact blocks.
