ABB LDGRB-01
Functions and Applications:
Ground fault monitoring: The ABB LDGRB-01 is a compact, DIN rail mountable device designed to provide reliable ground protection for ungrounded AC and DC systems.1 It is primarily used to monitor leakage current through fault flow to ground and to trip circuit breakers when a fault is detected, thereby protecting equipment and personnel from electrical hazards1.
Applications: The equipment is widely used in industrial automation, power systems, buildings and other places requiring ground protection12.
