Single-phase short-circuiting device for the third rail of the subway

.

SKU: Msp - CM - 120/1,5 - S3/ps
Category:

Application: from the ground, by positioning the phase clamp on the third rail, followed by the tightening of the clamp on it. The phase clamp must be handled using an insulating stick corresponding to the voltage of the installation.

Components:

  • Special clamp for the third rail – 1 piece
  • Earthing cable – 1 piece
  • Earthing clamp for the connection to the rail (CLPS) – 1 piece
  • Bayonet-hook adaptor (AF E-K) – 1 piece

Packing: waterproof bag.
