The switch-on pulse current limiter EBN U2 (compact flush-mounted version) is used when relay contacts weld due to high switch-on current peaks. Electronic ballasts, fluorescent lamps, energy-saving lamps etc. and of course the use of compensation capacitors cause switch-on current peaks of well over 100A! If the EBN U2 is connected downstream of the endangered contacts, current peaks are reduced to a non-critical value., Dimensions: 43x43x18.5mm, 230V AC - 1S 16A, tv - 15ms
