Slim rectangular shunt capacitors
BSMJ-C/D self-healing shunt capacitors use metallized film in rectangular cases for low-voltage power factor correction. The model schedules below cover 400V and 450V three-phase configurations from 12.5kvar to 80kvar. Match the voltage, output, capacitance, current and enclosure dimensions for the selected capacitor step.
