Frako 3 Phase Capacitors DD60 / DP60  Type LKT

Frako 3 Phase Capacitors the Safer, Stronger Capacitors for Power Factor Correction and Harmonic Filters. 

Hans von Mangoldt logoFRAKO 3 Phase Capacitors are ideal for power factor improvement, tuned filters and other power quality filter systems.  Capacitor Type LKT is available
in DD60 (240-660V) and DP60 (690-800V). Both offer safer, stronger features.
         240V, 480V, 600V, 690-800V 

The DD60 capacitors are designed for real world conditions.  They are designed for high ambient temperature (up to 60°C continuous) as well as high harmonic current.  DD60 capacitors can carry up to 165% of their nominal capacitor current, continuously giving high performance in harmonic environments.

DD60 offer continuous voltage capability of 110% of rated voltage makes them suitable for use either with or without a series reactor (tuning, de-tuning or filter). This unique rating is an industry first in power factor capacitor design and enables one capacitor to serve a multitude of applications.

The DD60 capacitors allow for a reactor to be retrofitted into an existing power factor system to block harmonics and prevent resonance.  The DD60 capacitors can be used with or without a series reactor in either power factor or harmonic filter systems minimizing stocking requirements.   

Triple safety protection and high current capability are combined to deliver dependable performance under extreme conditions. Below are the general specifications for Frako 3 Phase Capacitors – Go to each Frako Capacitor rating page 240V, 480V, 600V, 690-800V for a listing of Frako capacitors.
