Capacitor

Capacitors are essential passive components in electrical and automation systems, designed to store and release electrical energy in the form of an electrostatic field. In industrial contexts, these devices are characterized by parameters such as capacitance (measured in microfarads, µF), rated voltage (e.g., 400V, 690V), and dielectric type (e.g., polypropylene, electrolytic). They are used for power factor correction, harmonic filtering, energy storage in DC links, and motor starting applications. Capacitors can be single-phase or three-phase, with options for self-healing technology and integrated discharge resistors. Common configurations include cylindrical or rectangular enclosures with IP20 or higher protection ratings, and mounting options like screw terminals or busbar connections.

Capacitors are deployed across diverse industrial sectors, including manufacturing plants, power distribution substations, renewable energy installations (solar and wind), and commercial building automation. They are integral to power factor correction banks in low-voltage switchboards, DC bus stabilization in variable frequency drives (VFDs), and smoothing circuits in uninterruptible power supplies (UPS). In motor control centers, capacitors reduce reactive power demand, improving energy efficiency and reducing utility penalties. They also appear in lighting systems, welding equipment, and HVAC systems for power conditioning.

Within our catalog, key subcategories include power factor correction capacitors (e.g., series MKK, MKP), DC link capacitors for drives, and motor run capacitors. Main article codes often follow patterns like "B25667" or "MKK440-D-25" indicating voltage, capacitance, and series. For example, the MKK series offers compact designs for low-voltage networks, while MKP capacitors are suited for high-frequency applications. We also stock electrolytic capacitors for DC applications and film capacitors for AC filtering.
