Description The Générique DoepkeDRCBO 4 C20/0.03/3N-A is a four-module RCBO combining overcurrent and residual-current protection for three-phase systems. It features a 20 A nominal current rating with a C-characteristic tripping curve alongside 0.03 A residual-current sensitivity. The Type A detection handles AC and pulsating DC leakages in a 3P+N configuration. Its modular design mounts on standard DIN-rails for three-phase electrical panels.
