Export Batch Circuit Breaker Quality Issue Return And Exchange Case
Problem description
An overseas customer (**** Trading GmbH) purchased a total of 50,000 units of DZ47-63 C32 circuit breakers, shipped in 5 40-foot high-cube containers to Hamburg, Germany. During random inspection and installation after arrival, the customer found that approximately 3,800 circuit breakers had loose contacts and insensitive tripping when closing. Some products, upon disassembly, were confirmed to have deformed internal bimetallic strips, determined to be a batch quality defect. The customer requires return of the entire batch and compensation for installation labor losses.
Solutions
Our company immediately initiates the quality emergency process: 1) Arrange quality engineers to conduct a video conference with the customer to confirm the sealing of defective samples and issue a third-party inspection report; 2) Agree to recall and return all 50,000 units from the same production batch, replace them with new batch products, and upgrade the factory inspection standards (adding 100% closing/breaking aging test); 3) Bear the return freight from the destination port to the factory and 50% of the customer's labor costs for disassembly and reassembly; 4) Compress the delivery time for replacement products to 20 days, and provide 2,000 units of the same model as free spare parts as a subsequent quality guarantee.
Processing result
The customer accepted the replacement solution. The returned products were re-inspected by our company, and the defect rate was confirmed at 7.6%, which was attributed to a batch anomaly from the raw material supplier. The replacement products passed the customer's re-inspection, and no further complaints were received. Both parties continued cooperation, and the customer subsequently placed an additional order of 80,000 units, but required a third-party full inspection report for each batch.
Case Study Of Remote Installation, Debugging, And Support For 5,000 Waterproof Junction Boxes Provided To A Major Electrical Distributor In North America.
Problem description
The customer is a large electrical distributor in North America. They purchased 5,000 sets of outdoor waterproof junction boxes along with matching circuit breakers and distribution boxes in a single order, for use in multiple local commercial building renovation projects. Due to the tight project schedule and the fact that the customer's local installation team was unfamiliar with the internal wiring methods and sealing processes of the products, issues such as poor terminal crimping and torque deviations on sealing covers appeared early in the batch installation. The customer requires our side to provide remote technical support within 48 hours to ensure the installation quality of subsequent batches and avoid project delays.
Solutions
We have urgently assembled a three-person technical support team to provide standardized installation guidance via video conferencing and real-time online documents. Specific measures: 1) Record and send an English step-by-step installation video for this junction box model, focusing on terminal crimping tool selection and torque value settings; 2) Provide an illustrated torque parameter comparison table, clearly specifying the recommended torque range for sealing cover bolts and verification methods; 3) Support the customer's technical lead in using a mobile phone camera for live on-site connection, with our engineers checking each unit for abnormal operations and guiding adjustments to crimping plier models and operating techniques; 4) For the 327 units already incorrectly installed, provide remote disassembly and reinstallation guidance, and simultaneously supply a spare parts list so the customer can urgently source parts through local channels.
Processing result
After 48 hours of continuous remote support, all 5,000 sets of junction boxes and distribution boxes were correctly installed by the customer and passed on-site insulation and waterproof tests, with no parts lost during disassembly and reassembly. Subsequently, the customer placed an additional order for 2,000 sets of circuit breakers, added us to their list of qualified suppliers in the region, and established a long-term technical support service agreement with us.
Large-scale Distribution Box Product Overseas Installation And Operation Training Service Case
Problem description
The customer is an overseas large-scale engineering project contractor who purchased 5,000 sets of distribution boxes and matching circuit breakers in one order, with a total value of approximately USD 1.2 million. After the goods arrived at the port, the customer reported frequent circuit breaker tripping, terminal burnout, and other issues during installation and commissioning. The defect rate was as high as 8%, far exceeding normal levels, causing project delays. Remote troubleshooting revealed that the issues were not due to product defects, but rather that local installation workers were unfamiliar with the wiring methods, rated parameter matching, and operating specifications of the products, leading to widespread incorrect wiring and overload usage. Given that the second batch of orders is about to be shipped, the customer urgently needs systematic training support to resolve the installation and operation issues.
Solutions
Our company will immediately initiate the after-sales training service process, forming an after-sales training team composed of senior electrical engineers and developing a phased training plan: 1. Remote video training: Conduct 4 online live training sessions for client site engineers and construction team leaders, focusing on the internal structure of distribution boxes, circuit breaker selection and parameter matching principles, standard wiring procedures, and common error cases, while providing bilingual operation manuals and recorded videos. 2. On-site hands-on training: Dispatch 2 after-sales technical engineers to fly to the client's project location for a 6-day stay, conducting group hands-on drills for 120 local installation workers, demonstrating correct wiring methods hand-by-hand, and guiding workers to inspect and rectify each installed distribution box one by one. 3. Establish a long-term support mechanism: Open a dedicated technical consultation channel, provide 7*12 hour remote assistance, and add factory acceptance photos and videos delivered with the boxes before the second batch shipment, for reference during installation.
Processing result
After training and rectification, all on-site installation personnel passed the operational assessment, and all fault points in the installed distribution boxes were eliminated. The one-time pass rate for newly installed equipment increased to 99.6%. The customer was very satisfied with the training results, urgently placed an additional order for 3,000 distribution boxes, and proactively recommended this training case to other customers in the same industry. Both parties signed an annual technical training service agreement, further consolidating the long-term cooperative relationship.
