Function

– Three-phase, low-setting phase overcurrent device with timed or inverse definite minimum time (IDMT ) characteristics

– Three-phase, high setting phase overcurrent device with instantaneous or timed characteristics

Operation

– Low-level ground fault device with timed or inverse deterministic minimum time (IDMT) characteristics

– High-level ground-fault unit with instantaneous or definite-time operation

– Built-in circuit breaker fault protection

– Two heavy load relays and four signal output relays

– Matrix of output relays for routing the start or trip signals of the protection stage to the desired output relays

– Local display of measured values, set values and data recorded during faults

– Reading and writing of set values via local display and front panel pushbuttons or via the serial interface and fiber optic bus of the higher-level system

– Self-monitoring system for continuous monitoring of electronics and microprocessor operation

Microprocessor operation

– Powerful software support for relay parameterization, reading of measured and logged values, events, etc., and
