Description
Cross-sections range from 1.5–16 mm² for copper to 95–240+300 mm² for sector conductors. The enlarged heart-shaped conductor channel makes installation easier, because crushed or protruding conductor ends enter easily and do not catch. Shear bolts have one or two shear points, protrude minimally after installation, and the large hexagonal head does not jam in the tool. Instead of them, set screws with an internal hexagon can be ordered, which allow disassembly. A rotating friction disc at the base of the bolt does not damage the conductor wires and maintains contact pressure, and the transverse grooves of the channel break the oxide film and increase the pull-out force. The connectors come with an inspection hole or with an oil stop that blocks the path of liquid and gas. Lugs are made in standard and NEMA versions with two holes.
How to choose
The deciding parameters here are the cross-section and the conductor class. For copper 1.5–16 mm² there is a separate group, and for larger cross-sections four ranges up to 95–240+300 mm². An oil stop is taken where a barrier for liquid and gas is needed, and an inspection hole where it is important to see the conductor position. For taps without stripping the insulation, see the LV piercing connectors for 1–240 mm² or ISICOMPACT, and for connection to transformer bushings and busbars 2DIREKT up to 4 kA.

FAQ
What conductor cross-sections are these connectors designed for?
From 1.5–16 mm² for copper to 95–240+300 mm² for sector conductors, including classes 1 and 2 per EN 60228.
What standards are the connectors tested to?
To IEC 61238-1-1, mechanical class 1 and electrical class A. They are designed for heat-shrink joints per DIN SPEC 47640.
How does a connector with an oil stop differ from one with an inspection hole?
The oil stop serves as a barrier for liquid and gas, while the inspection hole makes it possible to see the conductor. Both versions come with shear bolts or with screws.
Are cable lugs available in standard and NEMA versions?
Yes, lugs are made in standard and NEMA versions with two holes, with shear bolts only.
