High-Current Power Distribution Protection

The ABB Emax 2 E6.2H/f platform is designed for high-current low-voltage systems where substantial fault-interruption capability and dependable circuit protection are required. With a 4000 A rated uninterrupted current, 100 kA ultimate breaking capacity at 440 V AC and 100 kA one-second short-time withstand capability, this breaker is well suited to critical distribution points exposed to high prospective fault currents.

The Ekip Dip LI electronic trip unit provides long-time overload and instantaneous short-circuit protection. This LI configuration is particularly appropriate where straightforward overload and rapid high-level short-circuit protection are required without dedicated short-time selective or integrated earth-fault functions.

Typical Applications

• Main incomer protection in high-current low-voltage switchboards.
• Industrial power-distribution systems.
• Transformer secondary distribution.
• Manufacturing and process plants.
• Large commercial electrical installations.
• Data centres and critical power systems.
• Utility and infrastructure electrical distribution.
• High-current switchboards requiring a fully rated fourth pole.
