DEIF RMC-121D Current relay
RMC-121D
Current relay
The RMC-121D combined short circuit and over-current relay is applied for protection of generators against both over-currents and short circuit currents.
The RMC-121D combined short circuit and over-current relay is applied for protection of generators against both over-currents and short circuit currents (I> + I>>).
RMC-121D has two sets of contacts.
