Screw lugs and connectors
Screw connectors are a reliable and economic way of connecting identical or different conductor cross-sections.
They can be used up to 36kV. All lugs and connectors are fitted with torque-limited shear-off screws.
The actual cross-section of the cable does not need to be known, because each screw lug or connector covers
many cable sizes. This results in simplified logistics, a small stock of lugs will cover a wide range of applications.
Also, the tin-plated surface means that they can be used on both copper and aluminium cables.
The principle of multiple tear-off screws
The screws of the Haupa screw lugs and connectors have a hexagon head and socket,
which clamps the conductor cross-section with optimal clamping torque and therefore reduces assembly time.
As the screw is tightened it will shear off when correct torque is reached and a good joint is made.

• simple assembly
• the screw head shears off when clamping
torque is right
• no torque key required
• screw can be detached using the
hexagon socket
1. The screw is fitted with several tear-off spots,
with different shear-off torque, a hexagon head
and socket.
2. The tear-off torques are defined in such as way
that generally the biggest conductor cross-section
is clamped with the biggest clamping torque and
the smaller conductor cross-section with the
smaller clamping torque. This happens by
allocating hexagon head and socket.
3. Assembly is much simpler than with the
telescopic screw, because each screw needs
to be pulled and torn off only once.
