Cast resin straight-through and branch joints

The new generation of straight-through and branch joints 
with WAGO COMPACT splicing connectors and 2-component PUR cast resin

Now NEW: Cast resin straight-through and branch joints

The new straight-through and branch joints with WAGO COMPACT splicing connectors can be used universally for cables and lines with insulation 
consisting of PVC, PE, VPE and EPR (e.g. N(A)YY, NYM). The straight-through joints can also be used for control and signal cables.

The joints are combined with the WAGO COMPACT 221 series splicing connectors provided by the market leader.

The complete set also includes the BBC Cellpack two-component PUR cast resin. It is available in a two-chamber bag, with resin and hardener kept apart by a separator. The cast resin component and reaction agent/hardener are always mixed directly in the bag before filling into the plastic shell. The two-component PUR cast resin is halogen-free and offers durable mechanical and reliable moisture protection. The set also includes the matching WAGO COMPACT splicing connectors. The joints are suitable for branch clamps for copper conductors.
