Jonas, a sourcing manager in Hamburg, received three apparently similar MCB samples from China. One had clear markings and a complete test report; another had a copied curve sheet with no traceable laboratory. His team changed the evaluation from unit price to evidence, and the compliant supplier won the framework order.<\/p>\n<p><strong>\u0645\u0644\u062e\u0635:<\/strong> Comparing MCB manufacturers requires more than a catalogue scan. Review the declared standard, tested breaking capacity, production controls, traceability, OEM process and after-sales documentation. IEC 60898-1 covers household and similar MCBs; destination markets may also require national marks or UL evaluation. Ask for current, model-specific evidence rather than generic certificates.
