YUANKY N7R Series Residual Current Circuit Breaker (RCCB) is a newly launched high-performance leakage protection device designed for global residential, commercial and industrial power distribution systems. Fully compliant with IEC/EN 61008‑1 standards, it operates at 50/60Hz, suitable for single‑phase 230V and three‑phase 400V circuits. This series provides rated currents from 16A up to 100A and residual sensitivity from 10mA to 500mA, available in 2‑pole and 4‑pole versions to satisfy various protection requirements.

The N7R RCCB adopts a pure electromagnetic structure with fewer components and no need for auxiliary power supply, ensuring stable performance unaffected by ambient temperature or lightning interference. Its compact structure, high reliability and long service life make it ideal for long‑term operation. The product supports Type A and Type AC leakage detection, as well as electromagnetic and electronic operating types, delivering strong compatibility for global markets.

The device uses a built‑in zero‑sequence current transformer to detect the vector difference between phase and neutral currents. Under normal conditions, the incoming and outgoing currents are balanced, and the breaker remains closed. When leakage, electric shock or insulation failure occurs, the current imbalance generates a signal that triggers the tripping mechanism. The breaker quickly disconnects the circuit to prevent electric shock, electrical fire and equipment damage, providing fast and effective personal and circuit protection.

Designed for easy installation, the N7R series supports 35mm DIN‑rail mounting and top/bottom wiring. It features IP20 protection, an operating temperature range of −25℃ to +40℃, 6000 times electrical life and 10000 times mechanical life. It is widely used in factories, commercial buildings, shopping malls, residential communities, power distribution cabinets and household electrical systems.

With high breaking capacity, stable performance and strict quality control, YUANKY N7R Series RCCB provides safe, reliable and cost‑effective leakage protection for customers worldwide. It is the preferred choice for professional installers, contractors and system integrators.
