BCH BOCR 2.0 microcontroller based motor protection relay for LV & MV motors, full load current range 2.5 to 60A, with ZCT/CBCT (earth fault). It has 3 output relays for trip and alarm and protects against overload, under current, short circuit, locked rotor, stall, unbalance, phase loss, phase reversal and CB failure, plus earth fault via external CBCT. Auxiliary supply 85V to 280V AC/DC; 35 mm DIN-rail or panel mounting.
