Description
The GEYA GYR9N Residual Current Breaker with Overcurrent Protection (RCBO) is a high-performance modular safety device designed for AC 50Hz circuits with a rated voltage of 240V and currents up to 40A. Engineered for versatility, it is ideal for terminal distribution lines in commercial office buildings, residential homes, and general industrial environments.
This series offers a customizable protection system supporting modular expansion, including auxiliary contacts, alarms, surge protection, and automatic reclosing devices. It features a robust 6kA short-circuit breaking capacity and instantaneous residual current protection (30mA sensitivity), ensuring rapid power cut-off to prevent electric shock and equipment damage.
Built for durability and compliance, the GYR9N meets IEC 61009-1 and GB/T 16917.1 standards. It boasts a mechanical life of up to 10,000 cycles, a rated insulation voltage of 500V, and an impulse withstand voltage of 4kV. The unit features an IP20 protection rating (upgradable to IP40), a wide operating temperature range (-15°C to 60°C), and advanced C65 technology architecture.
Installation is seamless thanks to a dual-busbar design and flexible wiring capabilities (supporting 1-25mm² copper/solid wires and 1-16mm² flexible wires). The intuitive split-handle design and color-coded window provide instant status visualization, clearly differentiating between overload/short-circuit tripping and residual current faults.
