• High set stage can be delayed up to 1 s for fuse selectivity coordination
• Reset ratio 95% enables a setting close to maximum load current
• Recovery time < 40 ms enables small time steps between time selective protection
• Low transient overreach i.e. the relay is insensitive to dc component in fault current. RXIDG 21H relay and assemblies
• Pioneering method for selective sensitive earth fault protection in solidly earthed systems
RXIIK-4–1MRK001643-AA
RXIDK 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 suitable for protection of a variety of power apparatus
including applications requiring coordination with existing time-overcurrent relays. RXIDK 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.
