Self Healing 3 Phase Power Factor Capacitor Tinplate Type 20kVar 450V Shunt Capacitor
BKMJ-0.45-20-3 20kVar 450V Three Phase PFC Capacitor
Product Introduction
The BKMJ-0.45-20-3 20 kVar PFC Capacitor is a BKMJ series self-healing shunt capacitor, mainly used for reactive power compensation in low-voltage power grids. It effectively improves the power factor, reduces reactive power loss, improves voltage quality and saves energy.
This PFC Capacitor is suitable for AC 50Hz, 450V low-voltage distribution systems. With tinplate shell with high mechanical strength, good safety and stable performance, it delivers reliable performance for capacitor banks, power distribution cabinets and industrial plants.
Product Features & Characteristics
Main characteristics of the 20 kVar 450V PFC Capacitor:
Metallized film electrodes with self-healing capability restore insulation after local breakdown, giving the PFC Capacitor a long service life.
A built-in pressure interrupter disconnects the element from the grid safely under fault conditions, providing high safety and reliability.
The built-in fast discharge module releases residual charge quickly after de-energizing, making installation and maintenance safer.
Advanced metallized film technology ensures low power loss, stable capacitance and stable performance over the whole service life.
Made of metal materials with a tinplate shell with high mechanical strength, good safety and stable performance, suitable for tough industrial environments.
Compact size and light weight simplify mounting in reactive power compensation cabinets and distribution panels.
Produced with advanced equipment and strict quality control to ensure consistent electrical performance of every PFC Capacitor unit.
The BKMJ series covers 1-50 kVar capacitor ratings for low-voltage power factor correction, reducing line loss and enhancing voltage quality.
