ABB Capacitors for LV Low Voltage Power Factor Correction


ABB CLMD03 LV capacitors is an extension of the ABB CLMD range. ABB CLMD capacitors provide high electrical performance and unique reliability for low voltage power factor correction.

ABB CLMD03 LV capacitors are made from 9 capacitor elements within an aluminium case. The case material and design enhance ventilation and maximise heat dissipation allowing as much as 50 kvar in a single case.

ABB CLMD03 LV capacitors are available in two three-phase designs: a single capacitor or two capacitors within the same housing.

ABB CLMD03 Low Voltage Capacitors

ABB CLMD03 is used for power factor correction, which provides the benefit of lower energy consumption. ABB LV capacitors use proven dry-type technology which prevents risk of toxic oil leakage. The aluminium case is recyclable and the vermiculite used is made of natural material.

ABB CLMD03 low voltage capacitors are available for 50 Hz and 60 Hz networks and network voltages 380v, 400v, 415v, 440v, 480v, 600v and 690v.
