Advanced 1000V DC Miniature Circuit Breaker for Enhanced Safety

The JCB3-63DC miniature circuit breaker provides powerful protection for DC systems and is suitable for photovoltaic arrays and communication networks. It has a breaking capacity of 6kA and contact indicators. It complies with the IEC 60898-1 standard and can provide reliable overload and short-circuit protection in 1-4 pole configurations.

Designed to meet the growing demands of modern DC power systems, the JCB3-63DC miniature circuit breaker can protect photovoltaic installations, telecommunication infrastructure and industrial DC circuits from electrical faults. By integrating advanced interruption technology, it can reliably isolate faults within milliseconds, minimizing downtime and equipment damage. Supporting up to 1000V DC voltage and up to 63A current, it is suitable for residential and commercial energy storage systems.

Safety is at the heart of our JCB3-63DC miniature circuit breaker design. A finely tuned thermal-magnetic trip mechanism detects abnormal current surges caused by overload or short circuit. A unique arc-extinguishing structure ensures rapid suppression of internal arcs, reducing the risk of fire in extreme conditions. A visible contact indicator provides instant, intuitive confirmation of operating status, allowing users to quickly assess system health without manual testing.

The JCB3-63DC miniature circuit breaker is versatile and available in 1 to 4 pole configurations to accommodate a variety of wiring methods while maintaining a compact size. Flexibility simplifies integration into existing switchboards or new installations. The 6kA breaking capacity exceeds standard requirements, ensuring reliable operation even in high fault conditions. Rugged construction materials resist corrosion and wear, extending service life in harsh outdoor or industrial environments.

The JCB3-63DC miniature circuit breaker is optimized for renewable energy systems by meeting the unique challenges presented by solar arrays. Fluctuating DC currents and changing environmental conditions require components that can operate reliably. The JCB3-63DC miniature circuit breaker’s low resistance contacts minimize energy losses and improve overall system efficiency. Compatibility with battery energy storage systems further highlights its role in modern green energy infrastructure.

Compliance with international standards and compliance with IEC 60898-1 specifications ensures consistent performance in global markets.
