FFF CompatibilityThe 3SU1 series is not backward-compatible with 3SB3 contact blocks and holders; you must use the 3SU1500-0AA10-0AA0 holder and new 3SU1 contact blocks. However, it fits the identical 22mm panel cutout.Features the same 22mm mounting diameter and a red 40mm mushroom-head actuator.Provides identical mechanical latching with a rotate-to-unlatch (twist-to-release) mechanism.Fits the standard 22mm/22.5mm panel hole but is mechanically incompatible with Siemens holders and contacts.Fits the same 22mm mounting cutout, though the red mushroom head is slightly smaller at 35mm vs 40mm.Features identical latching behavior with twist-to-release operation.
AI Summary

3SB30001HA20 by Siemens: Emergency Stop Switch Panel Mount, Front.

This is the official manufacturer-designated successor from the SIRIUS ACT 3SU1 series. It replaces the obsolete 3SB3000-1HA20 but requires a matching 3SU1500-0AA10-0AA0 holder and compatible contact blocks.

  • Official manufacturer-recommended successor series (SIRIUS ACT 3SU1)
  • Maintains the same Siemens brand quality and design aesthetics
  • Fits standard 22mm circular panel cutouts exactly
  • Requires purchasing a new holder (3SU1500-0AA10-0AA0) and matching contact blocks due to series incompatibility.

The Eaton RMQ-Titan M22-PVT is a robust and widely available alternative. It offers identical twist-to-release functionality and outstanding environmental protection ratings.

  • Space-saving construction with excellent front-of-panel seals
  • Superior environmental ratings (IP67, IP69K, NEMA 4X/13)
  • Attractive classical industrial aesthetic
  • Requires Eaton M22 series mounting adapters and contact blocks, and the mushroom head is slightly smaller at 35mm compared to the original 40mm head.

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.
