Arteche Mounting base for RD2 Relay Din Rail Type

TRIP RELAYS (I) Model
RD-2R
Applications
Intended for tripping applications where high demanding requirements in operating time
(with tripping time from 8ms to 3 ms) and breaking capacity are needed, that is the case of tripping HV and MV circuit breakers.
High burden configuration
