DV AVERES residual current devices (RCD) are designed to protect people from electric shock when touching exposed wiring or energized electrical equipment, and to prevent fires caused by prolonged leakage currents and resulting short-circuit currents. To protect against overload and short-circuit currents, residual current devices must be used in conjunction with circuit breakers. Warranty obligations are 10 years.
