FFF CompatibilityUtilizes the same standard housing footprint that snaps into the 3SU1 mounting collar.The module uses the same physical width and depth profiles for standard mounting.Contains 1 NC contact which matches the electrical requirements of the target. The auxiliary NO contact can simply be left unused and unwired.Mounts directly into the standard 3SU1 mounting collar and aligns with the actuator. The physical mounting mechanism is identical to the single-contact version.Shares the standard housing layout compatible with SIRIUS ACT systems, though it integrates two contact elements in the unit.Provides a DPST-NC contact configuration; one NC contact can be wired to exactly match the original 1 NC circuit, while leaving the second NC contact unwired.
AI Summary

3SU1400-1AA10-1CA0 by Siemens: Configurable Contact Block SPST-NC 10A @ 500VAC.

This alternative provides one normally closed (1 NC) and one normally open (1 NO) contact in a single block. You can use it as a substitute by wiring only the NC contacts and leaving the NO terminals open.

  • Provides the identical screw terminal connection style
  • Directly mounts to the standard Siemens SIRIUS ACT 3SU1 holder system
  • Offers a split 1 NO + 1 NC configuration
  • Provides an extra NO contact which may be redundant for single-channel applications

This variant provides two NC contact elements instead of one, using the same screw terminal style. It serves as an excellent alternative since you can wire just one of the NC contacts to replicate the original behavior.

  • Uses the identical screw-type terminal connections as the original block
  • Direct physical compatibility with the Siemens SIRIUS ACT 3SU1 mounting collar
  • Provides two independent NC contacts (DPST-NC) instead of just one
  • Higher unit cost due to double the contact elements
  • Slightly different wire entry positions due to the two-tier layout for the extra contacts

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.
