MKK440-D-56-21 power capacitor

The Epcos-TDK cosine capacitor series PhaseCap HD series is a continuation of the PhaseCap MKK AC series.These capacitors have a power range (frequency of 50 Hz) from 40 to 60 kVar.The capacitors of this series are specially designed for reactive power compensation devices, the main factors of which are long service life, constant capacity and the ability to withstand inrush currents up to 200 x In.This type of MKK AC capacitor increases the installation density of the steps of the reactive power compensation unit, thereby reducing the number of components and the total cost (for example, the control step containing one capacitor in a 50kVar cylindrical aluminum housing).These capacitors operate reliably and are easy to install (for fixing the Epcos capacitor to the mounting surface and grounding at the bottom of the housing, providing a bolted connection M12 - torque of 10N?). M）。Capacitors can only be installed in an upright position.The connection of the terminals must be done by a flexible conductor.When installed between condensers, a distance must be provided to provide cooling conditions (at least 20 mm in the case of free cooling).Since the vertical elongation of the housing (special expansion flange) triggers the overvoltage safety lock, the free space above the capacitor must be kept at least 20 mm high.Capacitors can only be installed in an upright position.The connection of the terminals must be done by a flexible conductor.When installed between condensers, a distance must be provided to provide cooling conditions (at least 20 mm in the case of free cooling).Since the vertical elongation of the housing (special expansion flange) triggers the overvoltage safety lock, the free space above the capacitor must be kept at least 20 mm high.Capacitors can only be installed in an upright position.The connection of the terminals must be done by a flexible conductor.When installed between condensers, a distance must be provided to provide cooling conditions (at least 20 mm in the case of free cooling).Since the vertical elongation of the housing (special expansion flange) triggers the overvoltage safety lock, the free space above the capacitor must be kept at least 20 mm high.
The capacitors of the PhaseCap HD series are produced according to the patented manufacturer of MCC technology - a combination of planar and "wave" cutting of the edge of a single-sided metallized polypropylene film that increases the contact surface area of the electrode.
