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 is the difference between a 1P miniature circuit breaker and a 2P miniature circuit breaker?
A:
A 1P miniature circuit breaker only controls one live wire and is used to protect the live wire in a single - phase circuit from overload and short - circuit faults. The neutral wire is directly connected without being controlled by the circuit breaker; a 2P miniature circuit breaker can control both the live wire and the neutral wire, and can cut off both in case of a fault, which is safer. It is suitable for scenarios that require disconnecting the bipolar power supply at the same time, such a
Q:How to choose the tripping characteristics (Type B/C/D) in a 1P miniature circuit breaker?
A:
Type B: The tripping current is 3 - 5 times the rated current. It is sensitive to short - circuit current and suitable for purely resistive loads (such as incandescent lamps, electric heaters). It can quickly cut off the circuit in case of a short circuit. Type C: The tripping current is 5 - 10 times the rated current. It is suitable for common mixed loads (such as mixed lighting and socket circuits). It can withstand a certain impact current to prevent false tripping when the equipment starts.
Q:Can a 1P miniature circuit breaker be used with a residual current device?
A:
Yes, and it is widely used in household circuits. Usually, a 1P miniature circuit breaker is used with a 1P + N or 2P residual current device. The 1P miniature circuit breaker is responsible for overload and short - circuit protection, and the residual current device is responsible for detecting leakage current (if it exceeds 30mA). They work together to protect line equipment and ensure personal safety.
Q:What should be noted when installing a 1P miniature circuit breaker?
A:
When installing, the following points should be noted: 1. Wiring Direction: Clearly marked "upper inlet and lower outlet", that is, the live wire of the power supply is connected from the upper inlet terminal, and the lower outlet terminal is connected to the load. Reversing the connection may affect the tripping performance or cause false actions. 2. Neutral Wire Handling: The neutral wire does not pass through the 1P miniature circuit breaker and needs to be directly connected to the neutral b
Q:What is needed for a detailed quotation?
A:
Please inform us of the current, voltage, number of poles, special requirements, etc.
