2DIREKT Pressure Screw With Ball Pin D25

PFISTERER offers special ball fixed points for 2DIREKT transformer terminal clamps for attaching earthing and short-circuiting devices.

This ball fixed point is suitable for all 2DIREKT clamps with a conductor cross section range of 35 – 240 mm2 and is designed with thread and pressure plate so it can be directly used for contacting instead of using a pressure screw. The assembly is only permitted either on a conductor or a spacer.

This version is suitable for uncovered and covered applications - provided that an appropriate cover with earthing possibility is available. The use with a cover is only possible by using a corresponding spacer.

In connection with a cover including earthing possibility the ball fixed point can be used in general for vertical and horizontal cable outlets. Excepted from this is the combination with a flat two conductor clamp (331 746 00X) including this ball fixed point and a fitting cover. In this case only a vertical cable outlet is possible.

The ball fixed points correspond in their dimensioning to DIN 48088 Part 1.
