AI-Powered supplier vetting

SummaryAswich Electrical Co., Ltd is an established electrical-component manufacturer founded in 1988, with more than 30 years of experience, a 30,000-square-meter production base, automated production lines, and stated annual DC isolator output of 1,000,000 pieces. It demonstrates broad customization capability, recent new-product activity, quality assurance, ISO9001:2015 and ISO14001 accreditation, and UL-related certification capability. Customer complaint handling is documented, but corrective and preventive actions for service capability lack written procedures or records. The supplier has valid manufacturing contracts with associated subcontractors but reports no inventory, overseas warehouse, overseas showroom, overseas agents, or branches. Financial information is present for multiple years, but the provided slices do not establish financial strength. No specific customer cases or named customers are supplied.

Supplier typeThe supplier is identified as an electrical and electrical-component manufacturer and seller, with experience manufacturing switches and circuit breakers since 1988. Its owned production base, laboratory, automated lines, and stated DC isolator output support classification as a manufacturer rather than only a trader.

CertificationsThe company is stated to hold ISO9001:2015 and ISO14001 accreditation, and its sustainable-development and product-certification capability lists UL and other certifications. These are explicit certification-related strengths, although the specific UL-certified products are not identified.

After-Sales capabilityThe supplier has a clear procedure and followed records for customer complaints, but it has no written procedures or records for corrective and preventive actions related to service capability. It also reports no inventory, overseas warehouse, overseas showroom, overseas agents, or branches, limiting evidence of local or rapid overseas support.

R&D capabilityThe supplier reports new products during the past year, high R&D investment, 50 total years of R&D engineer experience, and a national science and technology progress award. It does not provide an SDK and does not offer ODM services, but these limitations do not negate the explicit evidence of product R&D capability.

Production capacityProduction evidence includes a 30,000-square-meter plant, multiple automated production lines, an owned laboratory, valid contracts with each associated subcontractor, and stated DC isolator output of 1,000,000 pieces. Finished products are checked by packing staff, while no inventory capability is reported; overall manufacturing capacity is supported, but the inspection method appears limited in the provided information.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. This is reinforced by the listed design-service capability for customization from samples, demonstrating broad stated customization coverage.

Product Q&A

Q:How long is the delivery time for samples and regular orders?

For sample orders, delivery takes 3-7 days. For regular orders, we promise delivery within 15 days.

Q:What is the warranty period for this product?

We offer a 10-year warranty for this specific rapid shutdown switch. Generally, we provide 2-5 years depending on the product.

Q:Can I get a sample to check the quality before placing an order?

Of course! We think sample orders are the best way to build trust and verify quality.

Q:How do I choose the correct model of Rapid Shutdown Switches for my solar system?

Calculate based on panel voltage and quantity. For example, if panel VOC is 39V, max panels per route is 1000/39/1.15=22 pcs. Choose the pole count (2, 4, or 8) based on total panel quantity and string configuration.

Q:What is the difference between your product and cheaper suppliers?

Our DC Isolators are IP66/IP68 rated and high-quality customized for solar systems. We recommend comparing quality first, then price.
