Our 4-Step Quality Verification Process
At Konmask.com, we do not simply list and ship. Every TH-N12TP unit passes through our structured verification workflow before it reaches you:
- Step 1 — Source Authentication: All units are procured exclusively from authorized distributors or verified OEM surplus channels. No grey-market or unverified third-party sources.
- Step 2 — Physical Inspection: Each relay is inspected for label integrity, housing condition, terminal quality, and correct part markings against Mitsubishi’s published specifications.
- Step 3 — Functional Verification: Where applicable, units are bench-tested for trip response and auxiliary contact continuity prior to packaging.
- Step 4 — Traceability Documentation: Lot numbers, sourcing records, and inspection results are logged and retained. Documentation is available upon request for compliance-sensitive projects.
