RMC-111D Current relay

The RMC-111D short circuit relay is applied in cases where only protection against short circuit currents is required (I>>).

RMC-111D has one set of contacts.

RMC-111D

· Short circuit

· I>>: 100 to 400 %. <50 mS response time

RMC-121D

· Short circuit

· I>>: 100 to 400 %. 2 sets of contacts (parallel)

RMC-122D

· Short circuit and over-current

· I>>: 100 to 400 %, I>: 50 to 150 %

· Combined functionality

RMC-131D

· Differential current

· I>>: 100 to 400 %. 2 sets of contacts (parallel).

RMC-132D

· Over-current (double)

· I>: 50 to 150 %, I>: 50 to 150 %

· Simple current load sharing

RMC-142D

· Earth current (double)

· iE>: 10 to 110 %, iE>: 2 to 20 %

· Single phase measurement
