RZB-01

The RZB-01 relay is used for the detection of earth faults in DC distributions powered by accumulator batteries. Such distributions are usually not grounded, so a single ground fault does not pose a danger to the drive. Nevertheless, the fault should be detected and signaled in order to prevent its eventual transition into a double earth fault, which can cause significant damage. The RZB-01 relay reacts to single and multiple earth faults in DC circuits, either directly or via impedance such as a relay coil, signal bulb, etc., and enables their timely detection.
