Differential Relay
DESCRIPTION
Present the DER3B DUAL range, the new generation of type B differential relays with separate toroid. Recommended for electrical protection in the tertiary sector, where devices generating alternating, continuous or continuous type leakage currents are increasingly installed. mixed (inverter, soft start, UPS, electro-medical equipment such as MRI, CT scan, etc.). The large LCD display changes color based on the operating status and constantly monitors the differential current in TRMS with the novelty of displaying the differential current divided into AC and DC.
They allow adequate selectivity and differential protection to be achieved thanks to the wide adjustment of the leakage current threshold (0.05÷10/16A) and the trip delay threshold (up to 15 sec).
The Dossena DER3BDUALs are perfectly compliant with the strict regulations in force (IEC 60947-2:2019), thus satisfying a dual need: the safety of the system and the continuity of the service.
New technology, ease of use, great reliability, ease of installation and setup, performance and “user friendly” design.
Quantities and parameters are displayed on a large, very bright dot matrix display which changes color in relation to the operating status of the instrument (Green=measurement/monitoring, Blue=programming, Red=alarm/intervention).
