JUM8 Series Molded Case Circuit Breakers are specially designed for low-voltage distribution systems with limited installation space. This series is based on standard protection requirements and adopts a compact structural design, reducing the overall size while maintaining reliable performance. It is suitable for modern electrical installations where space efficiency is highly important.

Product Highlights：

1. Compared with conventional model enclosures, the size is reduced by 30%, significantly improving the space utilization rate of switchgear cabinets. It is especially suitable for data centers, photovoltaic combiner boxes, and other applications with strict installation space requirements, supporting higher-density circuit layout.

2. High-conductivity materials are used to optimize the internal current path, reducing heat generation by nearly 25%–30% during full-load operation. This allows the equipment to maintain stable performance even in high-temperature and enclosed cabinets, extending the system service life.

3. Equipped with both thermal protection and magnetic protection, it provides precise overload and short-circuit protection. Compliant with IEC/GB standards, the high breaking capacity ensures industrial-grade safety.

4. Advanced multi-blade contact design is used to quickly interrupt fault current and enhance arc-extinguishing performance. While reducing the product size, it still maintains a very high electrical safety margin.

5. Internally supports multiple accessories such as motorized operating mechanisms and shunt trips. It covers a wide rated current range from 100A to 1000A, meeting various customized configuration requirements
