Our Professional Service Case Studies
Issue:The Siemens frame circuit breaker has been in service for 20 years, reaching its end of life and posing a risk of failure. Since the busbar power cannot be disconnected, a new breaker must be installed matching the original model and dimensions.
Plan:Customized solution for this circuit breaker model and Siemens factory, enabling installation without altering the original busbar dimensions. Perfect fit, customer satisfaction guaranteed.
Effect:Satisfied
Issue:Multiple ABB low-voltage circuit breakers at the client's factory have been in operation for over 10 years. Some spare parts are no longer in production, and there is an urgent need to procure original-compatible spares to ensure ongoing maintenance support.
Plan:Batch source identical and compatible replacement parts through authorized OEM channels, provide complete certificates of conformity and warranty documentation, and assist customers in developing spare parts inventory management solutions.
Effect:All spare parts have arrived and passed acceptance, enabling the continuation of the customer's maintenance plan. Equipment availability remains above 98%, and annual spare parts procurement costs have decreased by approximately 12%.
Issue:Low-voltage circuit breaker in the production workshop failed to close, causing unplanned line downtime and significantly impacting production progress.
Plan:Engineer performed on-site troubleshooting with professional diagnostic equipment and identified a damaged main circuit breaker mechanism. Replaced with an original factory main mechanism and conducted more than 10 opening/closing cycle tests.
Effect:The device is back to normal operation. With zero faults over the past 30 days and unplanned downtime reduced by approximately 80%, customer production schedules are now secured.
