Operating principle
The relay contact (11 and 14) closes if the current is greater than the threshold.
The relay contact (11 and 14) opens if the current is less than 15 % (hysteresis) of the threshold.
Note :
Delay on pick-up (T1) 500 ms maximum. Response time to sensing (T2) 400 ms ± 50 %.
Response time to turn-off (T3) 120 ms ± 50 %.
The graduated set-point scale on the front relates to sinusoidal or delta current measurement. The
MCI can measure non-sinusoidal currents, for example currents subject to phase control. In this
case, the display may be affected by an error coefficient which is a function of the tripping angle of
the phase controller (form factor).
