PFC Capacitors

Class 5810

Low Voltage Fixed Capacitors

ReactiVar® fixed low voltage capacitors are ideally suited for power factor correction applications where the load does not change or where the capacitor is switched with the load, such as the load side of a motor starter. ReactiVar fixed capacitors are best suited for applications where there are no harmonic currents or voltages present.
For Fixed Capacitors suitable for use in harmonic-rich environments, contact your nearest Square D/Schneider Electric sales office.

Features:

●	Environmentally Safe: Reactivar capacitors are constructed with a dry type metalized Polypropylene capacitor element with no liquid dielectrics. There is no risk of fluid leakage or environmental pollution and no need for a drip pan.

●	Multiple Protection System: The patented protection system incorporates an internal protection device which negates the need for external fuses. Capacitor elements are encased in a non-flammable vermiculite filler as an added safety feature.

●	Low Loss, Long Life: The design features less than 0.5W/kVAR losses, including discharge resistors.

●	Attractive finish: Capacitor units feature a textured powder paint finish, ASA 49 gray. Units are constructed of 18 gauge steel and are suitable for floor or wall mounting.

 

Application Note: Capacitors are a low impedance path for the harmonic currents produced by variable frequency drives, motor soft starters, welders, computers, PLCs, robotics and other electronic equipment. These harmonic currents can be drawn into the capacitor causing it to overheat, shortening its life. Furthermore, the resonant circuit formed by shunt capacitors coupled with system inductances (motors and transformers) can amplify harmonic currents

and voltages in the electrical network. This amplification can cause nuisance fuse operation and/or damage to electrical equipment including capacitors and other electronic devices. If power factor correction in the presence of harmonics is required, please contact your nearest Square D/Schneider Electric sales office for assistance.
