Three-phase short-circuiting device for 0,4 / 6 kV electric motors

.

SKU: Msp - M - 3xSf/lf - Sp/Ip - S/p
Category:

Intended use: earthing of electrical motors terminal or of their power supply cables.

Application: manual, in two ways:

  • by the application of phase terminals of short-circuiting devices to the supply cable terminals of motors
  • directly to the cable terminals of motor supply cables

Components:

  • Phase terminal – 3 pieces
  • Fasteners (screws, Grower washers, nuts) – 3 sets
  • Short-circuiting cable – 3 pieces
  • Earthing cable – 1 piece
  • Manual earthing clamp – 1 piece

Packing: waterproof bag.
