What are the dimensions for different pole configurations?

Dimensions vary by poles: 1P is 36*104*75mm, 2P is 54*104*75mm, 3P+N is 72*104*75mm, and 4P is 90*104*75mm.

What should be done if the AFCB frequently trips?

Disconnect appliances and switch off lights to check for wiring issues; if it continues to trip, it may need replacement.

AI-Powered supplier vetting

SummaryZhejiang Leidun Electric Co., Ltd. is a China-based manufacturer/factory operating in the electrical and electronics sector. The supplier demonstrates broad customization, 3D software design, R&D, ODM, and OEM capabilities, including new product development and technical support. It reports valid manufacturing contracts, in-stock capacity, documented supplier-service procedures, and lead times within 15 working days in both peak and off-season periods. It holds CCC, CQC, and three system certifications according to its company description. However, it has no available SDK, overseas warehouse, overseas agents or branches, overseas showroom, or offline trade-show participation. Finished-product inspection is guided by instructions but lacks written records. Financial information is limited to year labels without performance figures, so financial credibility cannot be fully assessed. Customer approval and positive feedback are reported, but no specific customer names or case details are provided.

Supplier typeThe supplier is identified as Zhejiang Leidun Electric Co., Ltd., a limited company and manufacturer/factory based in Zhejiang, China, operating in electrical and electronics. This directly establishes its legal form, location, and business type.

CertificationsThe company states that it has obtained CCC and CQC certifications, as well as three system certifications and multiple honorary awards. These stated certifications support a positive assessment, although the specific system certifications are not identified.

After-Sales capabilityR&D responsibilities explicitly include technical support for after-sales service, sample proofing, and testing. The supplier also reports written procedures and followed records for assessing effective supplier service capability, but the slices do not describe response coverage, warranty terms, or dedicated after-sales infrastructure.

R&D capabilityThe supplier reports professional technical R&D capability, new product development during the past year, ODM services, and R&D engineers responsible for process development, technical improvements, product optimization, and technical problem handling. However, it has no available SDK, which limits evidence of software-development extensibility.

Production capacityThe supplier reports valid manufacturing contracts with each associated subcontractor, in-stock capacity, 300 qualified suppliers for service capability, and average lead times within 15 working days in both peak and off-season. Its finished-product inspection method has instructions but no written records, indicating a documented-process weakness in quality inspection evidence.

Customization capabilityThe supplier supports customization from samples, designs, full customization, minor customization, and flexible customization, and also provides 3D software design, ODM, and OEM services for well-known brands. These capabilities directly support a strong customization assessment.

Client casesThe company states that market sales data confirm its products meet customer needs and project requirements, with customer approval and positive feedback, and it reports OEM service for well-known brands. No named customers, project descriptions, or independently detailed case evidence are provided.
