AI-Powered supplier vetting

SummarySDKC Shandong Kaichuan Electric Equipment Co., Ltd. is described as a high-tech enterprise integrating R&D, manufacturing, trade, and service, with products including electrical control cabinets, motors, frequency converters, electrical components, and high- and low-voltage switchgear. It reports broad customization and ODM capabilities, new products within the past year, and OEM service for well-known brands. Its finished-product inspection instructions are reportedly uniformly followed, while service procedures exist for supplier assessment, corrective actions, and complaints; however, written records are absent for the latter two mechanisms. The supplier reports no overseas warehouse, showroom, agent or branch, or offline trade-show participation, and lists zero overseas service countries. Financial credibility cannot be confirmed because the provided financial fields report zero operating revenue, costs, profits, margins, and ratios for the stated periods, without enough context to validate the...

Supplier typeThe supplier is described as a high-tech enterprise integrating R&D, manufacturing, trade, and service. Its stated business scope centers on producing, processing, and selling electrical control cabinets, motors, frequency converters, switchgear bodies, transformers, and related electrical equipment.

After-Sales capabilityThe supplier has written procedures and records for assessing effective service capability, and reports lead times within 15 workdays in both peak and off-season periods. However, corrective and preventive action and customer-complaint procedures have no written records, while overseas service coverage is limited: zero countries and no overseas warehouse, showroom, agent, or branch.

Financial creditThe supplier reports registered capital and describes itself as a large-scale enterprise, but the financial-capacity slices report zero operating revenue, costs, profits, margins, and current ratios for the stated periods. These figures provide no positive evidence of financial strength and raise a material credibility concern, although the supplied data does not explain whether the zeros reflect actual results or incomplete reporting.

R&D capabilityThe supplier reports R&D capability, at least one new product during the past year, and ODM services. Its company description also identifies R&D as part of its integrated operation, but no usable SDK is available.

Production capacityThe supplier states that it operates manufacturing facilities and equipment including copper-bar processing machinery and an assembly line. Its described production scope covers electrical control cabinets, motors, frequency converters, switchgear, transformers, and related equipment, while finished-product inspection instructions are reportedly available and uniformly followed.

Customization capabilityBoth relevant slices explicitly list customization from samples, designs, full customization, minor customization, and flexible customization. The supplier also reports ODM availability, supporting broad product-development and customization coverage.

Product Q&A

Q:What should be paid attention to when wiring the 2P leakage miniature circuit breaker?

When wiring, you need to pay attention to: 1. Incoming and outgoing line direction: Most products are marked with 'upper in and lower out', that is, the live wire (L) and neutral wire (N) are connected from the upper part, and the lower part is connected to the load. 2. Neutral wire identification: The neutral terminal is usually marked with 'N'. It is strictly forbidden to reverse the live wire and neutral wire (which may cause the leakage protection to fail). 3. Grounding requirements: Ensure

Q:What is the core function of the 2P leakage miniature circuit breaker?

2P represents two poles, which can control the on-off of the live wire (L) and neutral wire (N) at the same time, and has three functions: overload protection, short circuit protection and leakage protection. Leakage protection principle: By detecting the current difference (residual current) between the live wire and the neutral wire, when the leakage current exceeds the rated value (such as 30mA), it will trip quickly within 0.1 seconds to prevent electric shock or electrical fire.

Q:How to test the leakage protection of the leakage circuit breaker?

We will test the leakage protection of the miniature leakage circuit breaker by means of leakage tester detection, test button test, grounding resistance tester, parameter setting test, etc.

Q:What certifications does this circuit breaker have?

The product is certified by VDE, ISO9001-2000, CE, CB, and CCC, ensuring compliance with international quality and safety standards.

Q:Is customization available for this product?

Yes, we offer flexible customization options including full customization, minor customization, and customization from samples or designs.
