3 PHASES POWER FACTOR CORRECTION CAPACITORS TECHNICAL SPECIFICATIONS
3 PHASES POWER FACTOR CORRECTION CAPACITORS TECHNICAL SPECIFICATIONS
- General Features: Cylindrical aluminum case, low losses, self-healing polypropylene film, high dielectric strength, 100,000 hours lifetime, environmentally friendly (no PCBs, Pb-free).
- Application: Power factor correction, harmonic filtering.
- Construction: Metallized polypropylene film dielectric, overpressure disconnection system, internal discharge resistors, cylindrical aluminum can, polypropylene resin fill material (UL 94V2), universal screw connection, M12 bolt fixing system.
- Technical Standards: IEC60831-1, NOM-003-SCFI-2014.
- Electrical Specifications: Working voltage ranges from 220-690 VAC, frequency 50/60 Hz, power tolerance -5% to +10%, operating temperature -25 to +55°C, dielectric losses <0.2 W/kvar, total losses <0.5 W/kvar, maximum overvoltage 1.1UN, maximum overcurrent 1.35IN, internal triangle connection, connection terminals max torque 5 Nm, fixed bolt max torque 9 Nm, connection cable max diameter 6.5 mm (AWG 2 max).
- Permissible Voltage Levels: Continuous at 1.00 UN, 8 hours at 1.10 UN, 30 minutes at 1.15 UN, 5 minutes at 1.20 UN, 1 minute at 1.30 UN.
- Various codes with specific capacitance, power (kVAr), current (A), and size (mm) for different voltage levels (220V, 230V, 240V, 380V, 400V, 415V, 440V, 460V, 480V, 525V).
- Mechanical fuse on cover, verified with IEC 60831-2, no additional folds needed.
- Install rejection reactors if voltage harmonics >5% or current harmonics >20% (IEEE 519).
- Use contactors with pre-insertion resistors to avoid in-rush current.
- Ensure dry installation site, use cold ventilation if in a cabinet, maintain 60 mm distance between capacitors, use cables for 1.5 times nominal current, verify capacitor discharge before handling, avoid hot spots, use isolated cables for arrays, adjust nut to max torque 9 Nm.
Final Disposition: Capacitor waste is considered dangerous and must be solidified, stabilized, or encapsulated by a licensed company.
Revision History:
- Multiple revisions from 2015 to 2018, including updates to certifications, specifications, sizes, and images.

Installation recommendations In order to do an appropriate installation of Capacitor's Banks you should follow below recommendations: • The Capacitor could amplify harmonic current if they are not specified appropriately. If the system has voltage harmonics higher than 5% or current harmonics higher than 20%, must install rejection reactors (IEEE 519) • In order to avoid In-rush current is recommended to install contactor with pre insertion resistors • The installation site has to keep dry • If capacitors are installed in a cabinet must install cold ventilation • Maintain at least 60 mm of distance...
