Earthing & Short Circuit Protection Equipment (662 PATC-MPU)

The 662 PATC-MPU Earthing & Short Circuit Protection Equipment is designed for medium voltage substations to ensure maximum operator safety during maintenance and repair works. It provides essential protection against accidental commissioning or voltage return, guaranteeing reliable grounding performance in compliance with IEC 61230 international standards.

The system features robust MPU aluminium alloy screw clamps that can be securely fixed to bare cylindrical conductors, flat bars, bending bus-bars, or earthing points. The screw-tightening mechanism ensures firm electrical contact and stable grounding in all environments. Available with Bayonet (MPUB) or Hexagonal-12 (MPU/H) fixing options for flexible installation.

This complete earthing kit includes PVC-insulated copper cables, a trifurcating connector, earthing lathe, and a telescopic pole, all neatly packed in a durable plastic carrying case for easy transport and field use.
