Single-phase short-circuiting device for round section bars

.

SKU: Msp - Cr - Sp/lp - O/p , Msp - CA - Sp/lp - O/P
Category:

Application: from the ground, by hanging the phase clamp on the round section conductor, followed by the tightening of the clamp driving screw.
Classic / automatic phase clamps must be handled using an insulating stick according to the voltage of the installation, provided with “RO bayonet’’ coupling system.

Constructive  phase clamps:

  • Classic reduced clamp (Cr)
  • Automatic clamp (CA)

Components:

  • Phase clamp – 1 piece
  • Earthing cable – 1 piece
  • Earthing clamp – 1 piece

Packing: waterproof bag.
