System role

This section explains what the product does and where it acts in the surrounding system.

Function
Switches trip signals through its changeover contacts in a protection circuit.
System position
Within a protection circuit, the relay sits between trip logic and the downstream switching or indication circuit.
Upstream / inputs
Trip logic supplies the upstream actuation signal to the relay.
Downstream / outputs
The eight changeover contacts provide the downstream switching interface.
Limitations
Unknown: installation fit, revision, condition and current availability require separate confirmation.

Evidence ledger

Facts, inferences, and unknowns are kept separate.

Facts

  • The captured listing identifies 7PA2642-1AA00-2 as a Siemens tripping relay with eight changeover contacts.

    Confidence: medium

    • pymatek.com — retrieved 2026-09-12; medium confidence

  • The listing specifies 220 V DC auxiliary voltage, a 10 ms standard tripping time and a 7XP9012-0 surface-mounting base.

    Confidence: medium

    • pymatek.com — retrieved 2026-09-12; medium confidence

Inferences

  • Within a protection circuit, the relay sits between trip logic and the downstream switching or indication circuit.

    Confidence: medium

    Rationale: The captured product function and system context establish the stated placement within the described system.
