Dreiphasen-Schutzdrossel

Dreiphasen-Schutzdrossel 14% (kapazitive Batterie-Nennspannung 480 V)

Chokes are assigned for operation in reactive power compensation systems to protect capacitive batteries. Together with capacitors, they form resonance systems which limit amplitude of harmonics currents.
It is possible to manufacture the chokes with various coil terminals like screw terminal blocks, cable lugs or copper bus bars, depending on the rated current. There is also a possibility to insert sensors in windings, in order to protect the chokes against overheating.
