Differential Relay
DESCRIPTION
The DER 4 series differential relays with separate toroid can be used on TT and TN type LV alternating networks.
They allow adequate selectivity and differential protection to be achieved thanks to the wide adjustment of the leakage current threshold (0.03=30 A) and the trip delay threshold (instantaneous=5 seconds).
The DER4s comply 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.
