Q with the addition of the Ekip Com in the circuit-breaker, you can:
– acquire and transmit a wide range of information via remote control;
– accomplish the circuit-breaker opening and closing commands by means of the motor
operator in the electronic version (MOE-E);
– know the state of the circuit-breaker (open/closed/trip) via remote control;
– setting the confi guration and programming parameters of the unit, such as the current thresh-
olds and the protection function curves.
