Advanced Generator LSIG Protection for 4000 A Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 protect major low-voltage electrical systems against damaging overloads, short circuits and earth faults while providing dependable high-current switching and isolation. The Ekip G Touch LSIG release combines long-time, short-time, instantaneous and ground-fault functions with generator-oriented protection capabilities, providing a comprehensive electronic protection platform for generation and critical distribution systems.

The E6.2H platform is engineered for demanding high-current installations. Its combination of a 4000 A current rating, 100 kA Icu at 440 V AC and 100 kA Icw for 1 s provides substantial interruption and short-time withstand performance, while the withdrawable architecture allows the moving part to be separated from its corresponding fixed section for inspection, servicing or replacement.

Typical Applications

• Generator protection and power-generation switchboards.
• Main incoming protection for high-capacity low-voltage switchboards.
• Industrial distribution systems with high prospective fault currents.
• Commercial and critical infrastructure power distribution.
• Transformer secondary protection.
• High-current feeders requiring selective LSIG protection and high short-time withstand capability.
