Capacitor

BSMJ self-healing power capacitors, 0.45-0.525 kV, 15-50 kvar, three-phase cylindrical cases for power factor correction panels. CE and RoHS certified.

Self-Healing Power Capacitors for PFC Panels

BSMJ capacitors use metallised polypropylene film with a self-healing dielectric, housed in cylindrical aluminium cases with an over-pressure disconnector. Ratings run from 15 kvar to 50 kvar at 0.45 kV and 0.525 kV, three-phase, for low voltage power factor correction panels and automatic capacitor banks.

Each unit is measured for capacitance tolerance, loss angle and voltage withstand before dispatch, and terminals accept cable lugs or busbar connection. Combine them with our JKW5C controllers for a complete compensation package, or ask us to size the bank from your load profile and target power factor.
