JCB3-80H Circuit Breaker Enhances Electrical Safety

The JCB3-80H circuit breaker series offers robust protection for diverse applications.With high breaking capacity and multiple accessory options, it ensures reliable performance and safety in commercial and industrial electrical systems, simplifying installation and maintenance.

A series of circuit breakers, the JCB3-80H, has been introduced, offering enhanced electrical protection and flexibility for modern installations. This robust component is designed to meet the rigorous demands of both commercial and industrial environments, providing a critical safety layer for electrical circuits.

The JCB3-80H is engineered for high performance. With a rated breaking capacity of 10 kA and energy limiting class 3, it can reliably interrupt high fault currents, minimizing potential damage to equipment and preventing fire hazards. The range of available rated currents is extensive, from a minimal 1A up to 80A, allowing for precise customization to protect everything from lighting circuits to larger machinery. Furthermore, it complies with international standards IEC/EN 60898-1 and IEC/EN 60947-2, assuring users of its quality and safety compliance.

Versatility is a cornerstone of its design. The breaker is available in multiple pole configurations, including 1P, 2P, 3P, and 4P, making it suitable for single-phase and three-phase systems alike. This flexibility ensures that engineers and electricians can find the right model for virtually any application. Its rated voltage of 230/400V AC aligns with common power systems across many regions.

Beyond its core function, the JCB3-80H is designed with usability in mind. Features like a clear contact position indicator allow for quick visual confirmation of the breaker’s status, enhancing safety during maintenance. The mounting on a standard 35mm DIN rail streamlines the installation process, saving valuable time in panel building.

A significant advantage of this series is its compatibility with a suite of accessories. The availability of auxiliary contacts, shunt releases, under-voltage releases, and alarm contacts means the breaker can be integrated into sophisticated control and monitoring systems. For instance, a shunt release can enable remote switching, while an alarm contact can signal when the breaker has tripped, facilitating faster response times in complex facilities.

The design also considers practical installation details. It accepts a variety of connection types, including cable, U-type busbar, and pin-type busbar, with clear specifications for terminal sizes and a recommended tightening torque of 2.5 N·m to ensure secure and reliable connections.

In summary, the JCB3-80H circuit breaker series represents a comprehensive solution for electrical protection. Its combination of high breaking capacity, configurable poles and current ratings, and extensive accessory support makes it a reliable and adaptable choice for safeguarding electrical infrastructure, contributing to both operational continuity and personnel safety.
