Configuration boundary
The record above gives only the facts that can be supported for 520422000. It does not decode every suffix or establish every rating of 520422000. Ask for the original datasheet or configuration printout when the installed assembly includes options, firmware, a trip unit, a cable, a sensor or an interface card.
For 520422000, compare the equipment tag and system drawings with the visible markings. Confirm supply, poles, contacts, protocol, measured range, nominal force or network role as applicable. Do not copy a value from a similar-looking code. If a number is missing, leave it open until the manufacturer record or actual nameplate resolves it.
Procurement and receiving notes
Request an offer for the exact 520422000 designation and required quantity. The offer should identify stock condition, manufacturer, document revision, included accessories and any exclusions. If the supplier proposes an alternative to 520422000, ask for a separate written comparison rather than silently accepting a different product family.
At receipt, inspect the 520422000 label, packaging and supplied accessories. Keep the serial or batch number when present. For a protection, safety or control component, preserve the old settings and approved wiring design before the existing 520422000 is removed.
Site acceptance
Install 520422000 only under the applicable isolation and safety procedure. Commissioning must test the specific installed function: switching or protection behavior, relay I/O, sensor response, communication, valve travel or cabling continuity as relevant. A visual match does not prove that 520422000 has the correct settings or compatibility.
Record the test result and exact 520422000 code in the maintenance file. If the part is obsolete or service status differs by region, verify stock and approved migration path with the manufacturer. Keep a separate note for substitutions because the replacement may require engineering changes.
Related-looking references
No additional unassigned 520-pattern designation is indexed with 520422000. A possible variant still needs its own exact-code check.
Release statement
Use 520422000 as the search and purchase reference only when the verified identity and the site's requirements align. Review each unconfirmed configuration item before issuing an order. This 520422000 record is an identification aid, not a substitute for the manufacturer manual or a site-specific engineering approval.
