Details

Short-circuiting bar with earthing cable on a switchgear installation
  • With longitudinal slot for reliable contact
  • For copper or aluminium busbars up to a thickness of 25 mm
  • For use with earthing sticks for hexagon or T pin shafts
  • Other bar and earthing cable lengths can be selected online via the earthing and short-circuiting configurator

The short-circuiting bar with longitudinal slot can be used for installations without direct neutral point earthing.
For connecting the earthing cable to the earthing system, it is fitted with a rigid ball head cap with a wing bolt for fixed ball points (Ø20 mm) (Part No. 772 312 (type KKH 20 FS)). Other equipment or cable lengths can be selected online via the earthing and short-circuiting configurator.
Short-circuiting bars are available with two different coupling mechanisms for earthing sticks:
