Power Capacitors Box Type

BOX TYPE CAPACITORS INDTECH Box Type Capacitors are high grade metalized polypropylene capacitor from 1-30 kVAr. These capacitors come with a biodegradable soft resin. These capacitors are self healing type. The capacitors come with an over pressure disconnector or dry and finger proof terminals. Capacitors are light duty power factor correction capacitors. These capacitors are meant for light and heavy duty application and are mainly used for industrial and heavy pump sets with a maximum of 5% harmonics. withstand capability.
