Earthing and Short-Circuit Protection Equipment (662 PATL-MPS/9510)

The 662 PATL-MPS/9510 Earthing and Short-Circuit Protection Equipment is specifically designed for high voltage overhead lines, offering maximum operator safety and full control during maintenance or repair operations. This advanced system ensures protection against accidental energization or voltage return, while its key-lock mechanism prevents unauthorized manipulation of safety components.

Engineered to comply with IEC 61230 international standards, the MPS clamp system allows secure fastening to cylindrical conductors (Ø 4–75 mm), flat bars (up to 80 mm), and flexible distribution bars (up to 80 mm) using screw-tightening clamps. With a short-circuit current capacity of 31.5 kA (120 mm² cable), this equipment ensures reliable grounding performance under demanding conditions.

Operators can perform the entire earthing maneuver using a single special pole (2.3 m) equipped with a key mechanism, ensuring safe, efficient, and controlled installation. The step-by-step locking sequence — including earthing lathe lock, clamp lock, and key recovery — provides maximum safety assurance and prevents accidental reconnection during field operations.

Key Features:

• High Voltage Protection – Designed for safe earthing and short-circuiting of high voltage overhead lines.

• Key-Controlled Safety System – Independent key mechanism prevents unauthorized manipulation and ensures full operator control.

• Versatile Clamping – Screw-tightened aluminium alloy clamps fit cylindrical conductors (Ø 4–75 mm), flat bars (max 80 mm), and flexible busbars.

• �� Quick Single-Pole Operation – Complete the entire earthing sequence safely with one control pole.

• High Short-Circuit Rating – 31.5 kA (cable 120 mm²) ensures reliable current discharge during fault conditions.

• � IEC 61230 Compliant – Certified for international safety and performance standards.

• Portable and Organized Kit – Includes dedicated storage bags for clamps, pole, and accessories for easy transport and handling.
