SOFAMEL - PATC-MPU | EARTHING & SHORT-CIRCUIT
 
The Sofamel PATC-MPU is a safety-critical grounding system designed specifically for medium-voltage substations. It protects personnel during maintenance and commissioning by providing a secure path to earth and enabling rapid short-circuiting of phases. This equipment prevents hazards caused by accidental energization or backfeed voltage, making it essential for safe isolation procedures.
 
Features & Benefits
 
A short-circuit current rating between 6.9 and 12 kA for 1 second ensures robust protection.
High quality copper cables available in sizes 25, 35, and 50 mm8 for optimal conductivity.
Aluminium alloy screw-type clamps compatible with conductors from 4 to 35 mm and busbars up to 45 mm.
Includes three-phase cables (~0.75 m), one earth cable (~2 m), and an insulated trifurcating connector for a comprehensive setup.
Compliant with IEC 61230 safety standards guaranteeing reliability.
 
Material & Build
 
The system is constructed with durable copper cables and aluminum alloy clamps designed for maximum conductivity and corrosion resistance. The insulated trifurcating connector ensures safe and efficient phase connection. All components are engineered for demanding substation environments.
 
Use Cases / Applications
 
Ideal for medium-voltage substations, switchyards, and industrial high-voltage systems. It is used during shutdowns, maintenance, and commissioning to ensure safe earthing and short-circuit protocols are maintained.
