Earth fault relay spaj 110 c without test adapter rs 421 010 aa ca da fa earth fault relay spaj 110 c including test adapter rtxp 18 rs 421 210 aa ca da fa the last two letters of the order number indicate the rated frequency fn and the auxiliary voltage uaux of the relay as follows.

The dc earth leakage relay detects leakages from dc power systems by measuring differential current between the ve and ve current carrying conductors. These relays work in conjunction with a separate external toroid. The signals from the sensors are processed by the detector unit and leakage is detected. Quality international approvals available for each range.

The new abb elr front panel residual current relays are tested for this purpose. Carrying out the protection thanks to the residual current relays it is possible to measure the leakage current to earth. Quick and fast wiring operation with cable and busbars. Thus leakage current if any will be dependent on the resistance value between respective terminals higher the resistance lower is the leakage.
