RXIDK 2H 1MRK000838-HA is a time-overcurrent relay mainly used as short-circuit and earth fault protection on all types of objects in the network. The available different time-lag characteristics and the short recovery times, together with the independent measuring element in each phase, ensures suitability on networks of major importance, where selectivity and short back-up tripping times are essential.

By selecting from six time characteristics available on the relay makes RXIDK 2H 1MRK000838-HA suitable for protection of a variety of power apparatus including applications requiring coordination with existing time-overcurrent relays. RXIDK 2H 1MRK000838-HA is directly replacing RXIDF. RXIDK has LEDs on the front for indication. The delay on the high set stage achieves selectivity on fuses. RXIDK has one fully isolated binary input. With the dip switch on the front it can be used to enable or block the relay, or raise the operate value of the low set stage (I>) with 40% for “cold load” restoration of a system
