The earth differential relays DER3B DUAL series is recommended for protection in the industrial and tertiary sectors, where are becoming more widespread the devices that generates alternating, continuous or mixed dispersion (inverter, UPS, electro-medical devices like MRI, C.A.T., etc.) which the normal leakage relays in class A-AC don't detect. The large LCD display changes color depending on the status of operation and continuously monitors the differential current in TRMS with the novelty of the current display differential divided into AC and DC.
