Low-voltage capacitors CLMD

Low-voltage dry capacitors for low power factor and power quality problems

As a source of reactive power, ABB low-voltage capacitors provide significant improvement of power quality and reduction in energy costs by:

  • Reducing or eliminating expensive utility penalties for low power factor 
  • Reducing power losses in cables and transformers
  • Increasing power transmission capacity in cables
  • Increasing available transformer capacity
  • Improving voltage stabilization in long cables

The CLMD capacitor family includes the following capacitor types: CLMD13, CLMD33S, CLMD43, CLMD53, CLMD63, CLMD83, CLMD03 and the CLMD03 power module (PMOD03).

The PMOD03 is an all-in-one compact and pre-wired power module (including capacitor, contactor, fuses and discharge resistor), especially developed to allow easy capacitor bank manufacturing with a significant cost minimization.

Applications
Low-voltage capacitor units CLMD are used in industrial and commercial installations.
