PRODUCT INTRODUCTION
The DZ47LED-2LNE is a high-performance Type A Residual Current Circuit Breaker with Overcurrent Protection, integrating comprehensive electrical safety functions into a single, compact device. Designed specifically for 120/240V split-phase (dual live wire) power systems, it features a 2P+N+PE wiring structure. This design ensures the simultaneous disconnection of both live conductors (L1, L2) and the neutral conductor (N) during a fault, while a dedicated protective earth terminal (PE) provides a reliable grounding path for enhanced safety.
This multi-functional device offers complete protection against earth leakage, overload, and short-circuit faults. It is engineered for regions utilizing low-voltage split-phase systems, such as North America, Japan, and Taiwan China. A key feature is its support for both Type A and Type AC residual current detection, providing flexibility for applications with different types of electrical loads. With a rated current range of 10A to 60A, the breaker delivers reliable, standardized protection for terminal circuits in residential, commercial, and light industrial applications.
