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

.

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

Intended use: earthing of the third rail of the underground.

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 installation.

Components:

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

Packing: waterproof bag.

Other equipment to be used in conjunction:

  • insulating stick type PMU 20-1 B/ba / PMU 20-1 B/baS
