Solution: Within 30 minutes: Confirm inventory - Our company always keeps the full series of ABB TMAX MCCB in stock, and the inventory of the models required by customers is sufficient Within one hour: Complete the quotation and order confirmation Customer: An automotive parts manufacturing enterprise Pain points: Pressure from production line shutdowns, difficulty in technical matching, and an extremely short time window
Case:On a Wednesday afternoon in March 2025, Wenzhou Guotuo Electric Co., Ltd., an authorized distributor of ABB Low Voltage Products, received an urgent call: a sudden failure occurred in the power distribution cabinet of a large automotive parts manufacturing plant, and 300 sets of Tmax molded case circuit breakers were in urgent need of replacement. The customer's production line was shut down, with losses amounting to hundreds of thousands of yuan for every hour of delay. From receiving the demand to completing delivery, Wenzhou Guotuo Electric Co., Ltd. (authorized ABB distributor) collaborated closely with the factory and completed the entire process from inventory allocation, logistics transportation to on-site delivery in only 24 hours, setting a new record for emergency supply response speed.
Emergency: Production Line Crisis
At 14:23 on Wednesday, March 12, during routine inspection, the customer's power distribution and maintenance personnel found abnormal temperature rise in multiple circuit breakers in No.1 power distribution cabinet of the welding workshop, with discoloration on the外壳 of some equipment. After urgent investigation by the technical team, it was confirmed that this batch of circuit breakers had severely aged internal contacts due to long-term high-load operation, posing risks of accidental tripping and even fire, requiring immediate replacement.
To make matters worse, the power distribution cabinet adopted an obsolete model from 8 years ago, which was basically discontinued in the market. The customer's original spare parts inventory was less than 20 units, while the actual number of circuit breakers to be replaced was as high as 300 units. This meant the customer had to find a matching alternative model and complete supply, installation and commissioning in the shortest possible time.
Customer Difficulties:
Production Line Shutdown Pressure:The welding workshop is the core production link for complete vehicle parts. Once the line is stopped, it will directly cause delays in the production plans of multiple downstream vehicle manufacturers.
Technical Matching Difficulty: The original circuit breakers were discontinued, requiring an alternative model with fully matching performance parameters.
Extremely Short Time Window: The customer only allowed a 48-hour window, otherwise huge liquidated damages would be incurred.
Solution: Upon receiving the customer's demand, Wenzhou Guotuo Electric Co., Ltd. immediately recorded the model, parameters and installation dimensions of the customer's original circuit breakers,
Contacted ABB technical experts to confirm the replacement solution (Tmax XT series is fully compatible)
Preliminarily confirmed the feasibility of 300-unit inventory
Within 30 minutes, the distributor synchronized the demand information to the ABB Low Voltage Products Business Unit Emergency Response Team and initiated the green channel approval process.
Technical Department Response:The original circuit breaker model was a certain brand T3 series 160A thermal-magnetic molded case circuit breaker, discontinued for many years. After rapid comparison by the ABB technical team, it was confirmed that Tmax XT1/T3 series could serve as a perfect replacement solution.
Key Technical Advantages:
Dimension Compatibility:Tmax XT series is fully identical in size to the original circuit breakers, requiring no modification to the power distribution cabinet and enabling in-situ replacement.
Performance Upgrade:XT series adopts new contact material, with electrical life increased by 30% compared with the original model.
Plug-and-Play:Identical terminal positions, reducing installation time by more than 50%.
After the technical solution was confirmed, the customer immediately issued a formal purchase order.
Within 30 minutes: Inventory confirmed - our company maintains in-stock availability of ABB TMAX MCCB full series, with sufficient inventory for the customer's required model.
Within 1 hour: Quotation and order confirmation completed.
Logistics:
Warehousing and picking completed before 17:00. At 19:15, a special vehicle loaded with 300 sets of Tmax molded case circuit breakers departed from the Shanghai Regional Center. A 4.2-meter van with dual drivers operating in shifts (vehicle non-stop, drivers rotating), covering a total distance of approximately 350 kilometers with an estimated travel time of 6.5 hours. The vehicle arrived at the customer's factory at 06:15 the next morning, 15 minutes earlier than expected. By 06:30, all 300 circuit breakers were unloaded. Inspection and acceptance completed at 06:45 with all products intact. Installation and commissioning of the first 50 units started at 07:00. From receiving the demand call to goods delivery, the total time taken was 16 hours, 32 hours earlier than the customer's required 48 hours.
Customer Evaluation:At the post-event review meeting, the Plant Equipment Director stated, "From receiving our call to delivering the goods, Wenzhou Guotuo Electric Co., Ltd., authorized ABB distributor, completed an almost impossible task within 24 hours. This is not only speed, but also professionalism and responsibility. At the most critical moment of the production line, Wenzhou Guotuo Electric Co., Ltd. was our most reliable partner. The delivery of 300 circuit breakers saved our production line and kept our promise to downstream customers."
