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 the Molded Case Residual Current Circuit Breaker 4P and the 3P molded case residual current circuit breaker?
A:
1. Different wiring methods: The Molded Case Residual Current Circuit Breaker 4P is connected to a three-phase four-wire system (L1/L2/L3/N) and controls the on-off of three live wires and the neutral wire at the same time; the 3P molded case residual current circuit breaker is connected to a three-phase three-wire system (L1/L2/L3) and only controls the on-off of three live wires. 2. Different neutral wire control: The Molded Case Residual Current Circuit Breaker 4P can cut off the neutral wire
Q:How to install and wire the Molded Case Residual Current Circuit Breaker 4P?
A:
Generally speaking, the incoming end of the Molded Case Residual Current Circuit Breaker 4P is connected to the three-phase live wires and the neutral wire, and the outgoing end is connected to the corresponding lines on the load side. During installation, ensure that the circuit breaker is installed firmly and wired correctly, and follow relevant electrical installation specifications. At the same time, pay attention to distinguishing the terminals with different functions to avoid incorrect wi
Q:How to test whether the leakage protection function of the Molded Case Residual Current Circuit Breaker 4P is normal?
A:
Usually, a dedicated leakage testing instrument can be used. When the residual current circuit breaker is in the closed state, simulate a leakage fault and observe whether the circuit breaker can trip within the specified time. You can also press the test button on the Molded Case Residual Current Circuit Breaker 4P to perform manual tests regularly to check whether the leakage protection function is effective. If the residual current circuit breaker fails to trip normally during the test, it in
Q:What is the function of the residual current circuit breaker?
A:
The residual current circuit breaker is mainly used to detect leakage (current leakage) in the circuit and quickly cut off the power supply when leakage occurs to prevent electric shock accidents or electrical fires. It can also provide overload and short-circuit protection.
Q:What is your delivery time?
A:
Depending on the order quantity, delivery can usually be completed within 12 days after receiving the deposit. We have an efficient production process and a complete supply chain system to ensure that we can provide customers with high-quality products on time.
