Wago 821-113

Suitable for main distribution boards with multiple RCD switches and appropriately sized small circuit groups; includes all necessary components for wiring the supply and connecting 14 single-phase AC circuits and 2 three-phase circuits.Ground fault potentials are supplied separately to each terminal block. Optional jumpers allow the ground fault potentials of adjacent terminal blocks to be bridged, enabling the formation of small circuit groups. N-potentials can be separated for insulation resistance measurement using knife disconnects within the multilevel installation terminal block.Contains:16 x multilevel installation terminal block; NT/L/PE; 4 mm² (2203-6641)2 x multilevel installation terminal block; L/L; 4 mm² (2203-6642)1 x end and intermediate plate (2203‑6692)3 x 2-conductor supply terminal block for distribution boxes; gray; 16 mm² (2016‑7601)1 x 2-conductor supply terminal block for distribution boxes; blue; 16 mm² (2016‑7604)1 x 2-conductor ground terminal block; green-yellow; 16 mm² (2016‑7607)1 x end and intermediate plate (2016‑7692)2 x screwless end stop; 10 mm wide (249‑117)15 x push-in type jumper bar; 2-way; light gray (2002‑402)2 x N/L test plug adapter; gray (2003‑499)2 x N test plug adapter; gray (2003‑500)2 x test plug adapter; for 4 mm Ø test plug (2009‑174)1 x marking strip; white; 0.5 m (2009-110)1 x WMB marker card; 1 … 50 (793‑5566)1 x WMB marker card; L1, L2, L3, N, PE (793‑5472)1 x felt-tip pen (210‑110)
