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:How can I get a quote for a CJ20 contactor?

If you require a quote for a contactor, please provide the required quantity, rated voltage and current, number of poles, contact material, etc. We will provide a quote based on your requirements.

Q:What is the rated current and voltage range of the CJ20 contactor?

Rated current: The CJ20 series covers 10A to 630A (specific models such as the CJ20-10 are 10A, and the CJ20-160 are 160A). Voltage range: Main contact rated voltage: 36V, 220V, 380V, and 660V (AC-3 load); Coil control voltage: Commonly 220V and 380V (customizable from 24V to 660V).

Q:How do I choose the appropriate CJ20 contactor model?

You can choose based on the load type: 1. Select by motor power (e.g., for a 7.5kW motor with a current of 15A, choose the CJ20-25, corresponding to 25A). 2. Select by actual current, leaving a margin. The recommended rated current is 1.2 to 1.5 times the load current to avoid overheating caused by frequent starting and stopping.

Q:What should I do if the contactor fails to close after the coil is energized?

We recommend troubleshooting the issue by following these steps: Measure the coil voltage to see if it's normal; Check if the control circuit fuse is blown; Manually press the contacts to confirm mechanical resistance (if any, lubricate or replace).
