Rapid connection 3. Variable and simple separation of N Plug in terminal 1.5 - 4 mm 2 Plug-in jumper HENPAS Solid conductors: Simply plug-in the conductor! Screw-type terminal 1.5 - 25 Flexible conductors: 1. Open the clamping unit with a tool. 2. Insert the conductor! Plug-in jumper Several N potentials are provided and linked by plug-in jumpers in the supplied state. N separation The N potential can be separated and reconnected via the plug-in jumper. 4. Good accessibility during connection Arrangement of the PE and N terminals in Mi Circuit breaker boxes: Technics Connection of solid and stranded conductors. connection of untreated, flexible conductors (without end ferrule). 2. More clamping units for practical use Terminals are fixed staggered in height More space when connecting the conductors: Removable N terminal for a simple connection of the conductors. Free accessibility of PE clamping units when inserting the conductors. The N terminal is then simply snapped in place.
