Key Features and Advantages: Industry-Leading High Interrupting Capacity: Rigorously tested and verified for repeated interruption at 10kA conditions. Resettable Fault Protection: Enables rapid system recovery after fault current occurrence, reducing vehicle breakdown time. As battery capacities in international automotive markets continue to increase, the demand for contactors' load-breaking capacity has also risen sharply, while the complexity of matching contactors with fuses has grown accordingly. Vicvac's Smart contactors with high interrupting capacity help automakers quickly and stably respond to severe short-circuit faults, ensuring vehicle and passenger safety, and solidifying and enhancing its forward-looking position in the global electric vehicle contactor market. Core Features: Utilize novel arc-quenching technology and high-temperature resistant insulating materials to quickly and stably interrupt 10kA fault currents under extreme conditions such as short circuits. Integrate overcurrent detection with configurable current trigger thresholds, enabling contactors to interrupt within as fast as 2ms, effectively reducing arc hazards and ensuring vehicle and personnel safety. Unlike one-time fuse technology, Smart contactors are resettable, allowing vehicles to quickly resume operation after fault clearance and extending operational time. Provide fault indication functionality, aiding system identification of fault types and accelerating fault clearance. Offer integrated temperature detection capabilities. Employ ceramic brazed sealing technology filled with a protective gas primarily composed of hydrogen, ensuring low and stable contact resistance. The intelligent contactor integrates contactor and fuse functions, significantly reducing component count, weight, and thermal losses. Currently, the Smart contactors have successfully passed on-vehicle testing on a 400V platform of a leading domestic automaker. Looking ahead, Vicvac will continue to increase R&D investment, focus on the intelligentization and integration of contactors, launch more innovative products to meet diverse market needs, further expand its global market share, and contribute solidly to the advancement of global electrification.
