Frako Capacitor Data and Specs:

  • The new DD60 capacitors are designed for real-world conditions such as high ambient temperature (up to 60°C continuous) and high harmonic current.  They can carry up to 165% of their nominal capacitor current, continuously giving high performance in harmonic environments.
  • Continuous voltage capability of 110% of rated voltage makes them suitable for use either with or without a series reactor (tuning, detuning or filter). This unique rating is a 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.  They can be used with or without a series reactor in either power factor or harmonic filter systems minimizing stocking requirements.
  • Frako DD60 capacitors include triple safety features such as all 3 phases disconnect at overpressure plus self-healing, segmented metalized film to protect against catastrophic failures.  The DD60 capacitors are dry-type no leak capacitors (with only a thin film of oil applied to metalized film where it is most beneficial) eliminating leakage of oil which can occur in traditional oiled filled capacitors. The cylindrical design uses optimized geometrical shape and conforms to industry best practices for internal heat dissipation.
  • Secure, maintenance free terminals, which offer anti-vibration connections and maintain terminal pressure for the lifetime of the capacitor, are factory installed on all DD60 capacitors.  Type DD60 are available in voltage ratings of 240/264480/528 and 600/660.  Request for Quote
