CONTROL

Virtual breaker control switch controllable from

both HMI and com. ports: 101

Four virtual selector switches controllable from

both HMI and com. ports: 43. 143. 243. 343

Communication port control of 101 and #43

switches allows for SCADA control of relay and

breaker.

INSTRUMENTATION

Real time A, B, C phase current, voltage; fre

quency; and derived neutral and negative

sequence current and voltage.

Real Time 3 phase Watts, VARs, and Power Factor.

REPORTS

Current demands for phase, ground, and negative

sequence currents, and forward and reverse Watts

and VARs magnitudes and time stamps are

recorded for today’s peak, yesterday’s peak,

and peak since reset.

kWh and kVARh, forward and reverse

Breaker operations counter and contact

interruption duty. Breaker operate time also available.

FAULT RECORDING

255 event sequence of events report with I/O and

alarm sub-reports

Fault Reporting; 1 or 2 oscillography records per

fault report

16 fault summary reports; two most recent Fault

Summary Records saved to non-volative memory
