Our 4-Step Quality Verification Process
Every ABB SPAJ140C shipped from Konmask.com passes through our standardized inspection protocol:
- Step 1 – Source Authentication: Units are procured exclusively from ABB-authorized distributors or verified OEM surplus channels. Supplier credentials are documented and on file.
- Step 2 – Physical Inspection: Housing integrity, label authenticity, serial number traceability, and connector condition are checked against ABB factory standards.
- Step 3 – Functional Bench Test: Relay pick-up thresholds, trip timing, and output contacts are verified using calibrated test equipment before packaging.
- Step 4 – Documentation Review: Original factory documentation, test reports, and warranty cards (where available) are included with each shipment.
Key Features & Benefits
