RXIDK 2H is a single-phase microprocessor based time-overcurrent relay that is available in multi-phase and earth-fault assemblies RAIDK. The RXIDK 2H has simple setting knobs and selector-switches for different inverse and fixed time delay overcurrent characteristics and operate values and time delays. It is used as short-circuit and earth-fault protection for all types of objects in the network.
The available time-lag characteristics and the short recovery times, together with independent measuring elements in each phase and for earth-faults, ensures suitability on networks of major importance, where selectivity and short backup tripping times are essential. It has four LEDs on the front for start, trip and self-supervision indication.
RXIDK 2H is pin compatible with the obsolete RXIDF 2H relays and is therefore offered as a replacement part.
