Product Introduction
The ETM7LE series RCBO (Residual Current Breaker with Overcurrent Protection) is a compact device that combines leakage protection, overload and short-circuit protection, and circuit isolation in one unit. It is ideal for low-voltage terminal distribution in residential, commercial, and industrial environments—including homes, offices, energy systems, communication facilities, lighting panels, and motor circuits.
By detecting leakage currents, the ETM7LE helps protect people from electric shock. At the same time, it safeguards electrical circuits and equipment from potential damage caused by overload or short circuits, making it a reliable safety solution.
