AI-Powered supplier vetting

SummaryWenzhou Yuanda Electrical Equipment Co., Ltd. is a China-based manufacturer established in 1993, with 280 employees, more than 10 production lines, 50 quality-control staff, and stated output capacities for voltage stabilizers, miniature circuit breakers, and AC contactors. The supplier reports ISO 9001:2015 certification and product certifications including UL, CE, and 3C, as well as design patent technology. Its stated processes include advanced design software, testing equipment, and controls from raw-material procurement through finished products. However, the available information does not verify contract manufacturing, inventory, overseas services, ODM/OEM, SDK, environmental, or fire-drill capabilities. No customer cases or financial-strength evidence is provided. The audit record identifies TUV Rheinland and a valid report period, but the audit result is recorded as “0” without an explained interpretation.

Supplier typeThe supplier is explicitly identified as a manufacturer and a limited company located in Zhejiang, China. It has operated since 1993, supporting classification as an established manufacturing supplier.

CertificationsThe supplier reports ISO 9001:2015 certification and product certifications including US UL, EC CE, and 3C; it also states that it has held an industrial production permit and received export-advanced-enterprise recognition for three consecutive years. A TUV Rheinland audit report is listed with dates from November 4, 2025 to November 3, 2026, although the recorded audit result of “0” is not explained.

After-Sales capabilityThe supplier states that its marketing center provides comprehensive pre-sale, in-sale, and after-sale service to customers worldwide. However, overseas warehouse, showroom, and overseas agent or branch capabilities are all marked unknown, so the depth and delivery model of after-sales support cannot be fully verified.

R&D capabilityThe supplier reports using PROE/CAD and other design software, integrating decades of low-voltage electrical manufacturing experience, and holding product design patent technology. ODM, SDK, private-mold, 3D-design, and new-product R&D capabilities are marked unknown, limiting confirmation of broader innovation services.

Production capacityThe supplier reports more than 10 production lines, 50 quality-control staff, and stated annual capacities of 1,000,000 voltage-stabilizer boxes, 5,000,000 miniature circuit-breaker boxes, and 2,000,000 AC-contactor bags. It also describes testing equipment and process controls from raw-material procurement through finished production, providing explicit evidence of substantial production and quality-control infrastructure.

Product Q&A

Q:What standards does your low voltage switchgear comply with?

Our switchgear is designed and manufactured in full compliance with the international IEC 61439 series of standards (specifically IEC 61439-1 & -2). We also hold complete Type Test Certification (TTA) from an independent, accredited laboratory to validate the performance and safety claims. Our products also meet relevant national standards such as GB7251.1.

Q:What is the meaning of 'Form 4B' separation?

Form 4B is a classification per IEC 61439 that specifies the highest degree of internal separation within the assembly. It ensures complete isolation between the busbars, functional units (like circuit breakers), and outgoing terminal compartments. This enhances safety by containing any potential internal fault arc, allows for safer maintenance, and prevents faults in one unit from affecting others.

Q:What is the advantage of a withdrawable circuit breaker design?

A withdrawable design allows for the circuit breaker to be easily disconnected, isolated, and physically moved to a 'test' or fully 'withdrawn' position without de-energizing the entire panel. This enables safe and rapid maintenance, testing, or replacement of the breaker, significantly minimizing downtime for critical power systems.

Q:What is the short-circuit withstand rating (Icw) of your panels?

Our standard panels are rated for a short-time withstand current (Icw) of 50kA for 1 second. This means the assembly can withstand the thermal and electromagnetic stresses of a short-circuit fault of that magnitude for the specified time, allowing the upstream protective device to clear the fault without catastrophic failure. Higher ratings can be engineered for specific projects.

Q:What is the typical delivery lead time for a custom switchgear project?

For standard configurations, the lead time is typically 4-6 weeks. For fully customized projects involving complex engineering, the lead time can range from 8 to 12 weeks. We provide a precise timeline upon finalization of the technical specifications and single-line diagram.
