Product Introduction
The ETM3LE series RCBO (Residual Current Circuit Breaker with Overcurrent Protection) is designed for use in low-voltage distribution systems, offering a combination of earth leakage protection, overload protection, short-circuit protection, and circuit isolation. It’s well-suited for a variety of applications, including residential buildings, industrial setups, energy facilities, communication systems, infrastructure, lighting networks, and motor circuits.
By detecting leakage currents, the ETM3LE helps protect individuals from electric shock. At the same time, it prevents damage to electrical circuits and equipment caused by overloads or short circuits, reducing the risk of secondary faults.
