ABB LDGRB-01 Ground fault monitoring device

The ABB LDGRB-01 is a compact, DIN rail mounted ground fault monitoring device designed to provide reliable ground protection for ungrounded AC and DC systems. It has the functions of load grouping, relay output, digital input and communication interface, which can group loads and control different equipment or systems as needed. It usually has multiple relay outputs for controlling various loads, such as motors, valves, lights, etc. In addition, it may be equipped with digital input channels to receive external signals or trigger conditions in order to perform corresponding control operations.

The device has a wide range of parameters, including motor power range (0.12 to 200 kW), torque range (85 to 18,000 nm), ratio range (5 to 28,000), input speed range (750 to 3000 rpm) and output speed range (0.05 to 500 rpm). It also has multiple mounting position options (M1 to M6) and ADAPTS to a wide ambient temperature range (-20°C to +40°C), with an IP55 protection rating.

In addition, ABB LDGRB-01 has A rated voltage of 380 V, rated frequency of 50 Hz, rated current range of 1.5 to 350 A, efficiency of up to 97%, and noise level of less than 80 dB. Its compact design and easy installation make it suitable for various industrial automation applications.
