capacitor box

A capacitor box is an electrical device used to house and protect capacitors, typically made of metal or flame-retardant plastic. It can accommodate single or multiple capacitors internally and provides terminal blocks, heat dissipation structures, and safety protection features. It is used for reactive power compensation, power factor correction, filtering, or energy storage applications. Capacitor boxes are widely used in distribution cabinets, motor starting circuits, lighting equipment, and electronic devices, featuring compact structure, easy installation, and high safety and reliability.
