ZN63A(VS1)- 12M Indoor Permanent Magnet Vacuum Circuit Breaker

Introducing our innovative product line featuring permanent magnetic mechanisms, specifically designed for efficient operation within a 12kV-rated voltage and 50Hz-rated frequency environment. With a broad range of rated currents from 630A to 3150A and short circuit capabilities ranging from 16kA to 40kA, these circuit breakers are engineered to meet diverse electrical demands seamlessly.

Designed to effortlessly integrate into KYN28 switch cabinets without requiring any modifications, this product combines cutting-edge technologies, including vacuum technology, permanent magnet mechanisms, and intelligent control systems. Building upon the established advantages of the ZN73 indoor vacuum circuit breaker, our product stands out with leading control technology and an extended service life.

Utilizing high-performance permanent magnet materials and advanced microcomputer design, our proprietary control technology fine-tunes the coil driving power of the permanent magnet mechanism. This optimization results in impeccable opening and closing curves for the circuit breaker, ensuring a soft landing and significantly reducing mechanical collisions. The innovative design mitigates the risk of mechanism deformation caused by collisions between moving and static conductive rods, as well as overtravel and distance changes during operation, eliminating the need for user adjustments.

With a service life extending up to an impressive 20 years and requiring no maintenance or adjustments during normal load current operation, this circuit breaker sets industry standards. Its ability to withstand frequent operations highlights its superior characteristics and reliability. Elevate your electrical systems with a product that not only excels in performance but also minimizes the need for user intervention, embodying the pinnacle of technological innovation in the industry.
