ABB RXPE40 INRK 511 011-FA Directional Current Relay+RXKL 1 1MYN563022-A TIMER
ABB RXPE40 INRK 511 011-FA plus RXKL 1 1MYN563022-A is combined power protection relay set for substation power distribution system. This power protection relay set provides directional overcurrent detection for overhead line and feeder protection. The power protection relay set matches perfectly with RXKL 1 timer module for time-delay tripping logic. This power protection relay set adopts modular COMBIFLEX design for flexible cabinet configuration.

It serves as core protection assembly for high voltage feeder control. The directional current relay identifies fault current direction to achieve selective protection coordination. The directional current relay quickly detects short-circuit fault and sends trigger signal to timer unit. The directional current relay supports stable operation under industrial substation electromagnetic interference. The directional current relay reduces unnecessary tripping caused by external network faults.

Rigorous IEC standard testing guarantees long-term dependable performance. The substation protection spare fits ABB COMBIFLEX relay rack for direct replacement. The substation protection spare is stocked for power plant and substation retrofit maintenance. The substation protection spare features adjustable time setting to coordinate with other protection devices. The substation protection spare minimizes outage risk of power transmission network.
