Type PFCS, 3-Phase AC Power Factor Correction Capacitors
Type PFCS 3-phase series capacitors are designed for power factor
correction in automatic PFC controllers. Each PFCS capacitor is
made with three self-healing metallized polypropylene windings,
connected in delta, enclosed in a cylindrical aluminum case and
filled with an environmentally friendly fluid.
Highlights
- For 3-phase AC Power Factor Correction
- Delta connected
- Discharge resistors included
- UL810 approved internal pressure interrupter

to ensure that the failure of an electrical component does not result in a risk of personal injury or property
damage. Although all product-related warnings, cautions and notes must be observed, the customer should
not assume that all safety measures are indicated in such warnings, cautions and notes, or that other safety
measures may not be required.
