821-129 TOPJOB®S main distributor set, RCD excl. Low Voltage

For the main distribution with multiple RCDs and correspondingly small circuit groups

Contains all necessary components for wiring an infeed and connection of 14 alternating current and 2 three-phase circuits The RCD potentials are fed in individually per terminal. By means of an optional jumper, the RCD potentials can be bridged across to adjacent terminals and small circuit groups can be formed. Disconnection of N potentials for insulation resistance measurement via insulating blades in the multilevel installation terminal
