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 active conductors that. The new abb elr front panel residual current relays are tested for this purpose. These relays work in conjunction with a separate external toroid.

Quick and fast wiring operation with cable and busbars. The dc earth leakage relay detects leakages from dc power systems by measuring differential current between the ve and ve current carrying conductors. Abb offers versatile range of din rail and panel mounting type earth leakage relays for various applications complying with iec 947. Thus leakage current if any will be dependent on the resistance value between respective terminals higher the resistance lower is the leakage.

The signals from the sensors are processed by the detector unit and leakage is detected.
