FFF CompatibilityThe 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.

  • Part of the exact same Siemens SIRIUS ACT family
  • Fully compatible with the same contact blocks and mounting holders (no redesign required)
  • Enhanced mechanical robustness due to metal collar construction
  • Slightly more expensive due to metal bezel construction

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.

  • Highly available and standardized industrial emergency stop design
  • Maintains the same 22mm cutout and 40mm red mushroom aesthetic on the panel front
  • Requires switching the behind-the-panel contact blocks and mounting collars to Schneider's system

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
