Capacitors type CPEFS 25 - three phase
 Capacitors type CUEFS 25 - single phase
 Capacitors type CUFFS 25 - single, live

Application

The capacitors are designed for power factor correction and harmonics filtration at medium voltage. They are all-film dielectric – polypropylene foil impregnated with an environmentally friendly, non-toxic biodegradable insulating oil. There is the aluminium foil as the electrodes. This construction assures minimal looses of the capacitors. Three-phase units are in star – Y connection, single-phase units are in I connection. The capacitors have internal discharge resistors.

Installation instruction
  • Impregnant is free from PCB and is completely non-toxic. It is very stable over a wide operating temperature range
  • All three-phase and single-phase units are in dead case
  • Single-phase units are available with two bushings or connected with a single bushing and live case
  • Low voltage pressure sensor 230 V, 50 Hz available
  • Terminal cover IP42 available
  • Stainless steel case, paint finish. For indoor/outdoor installation
  • Max torque – hollow studs M12 - 10 Nm
  • Max torque - earth connection M10 - 7 Nm
