Additional function

UA16 RA...UA30 RA series contactors for capacitor switching can be used for installations in which the peak current far exceeds 100 times nominal rms current., The contactors are delivered complete with their damping resistors and must be used without additional inductances, The capacitors must be discharged (maximum residual voltage at terminals <= 50 V) before being re-energized when the contactors are making
