Advanced High-Current Power Distribution Protection

The ABB Emax 2 E6.2V/f platform is designed for high-current low-voltage systems where exceptional fault-interruption capability and dependable electronic protection are required. With a 4000 A rated uninterrupted current and 150 kA ultimate short-circuit breaking capacity at 400 V AC, this breaker is particularly suited to critical distribution points exposed to very high prospective fault currents.

The Ekip Touch LI electronic trip unit provides adjustable long-time overload and instantaneous short-circuit protection. This LI configuration is suited to applications requiring sophisticated electronic overload protection and rapid interruption of high-level short circuits without dedicated short-time selective or integrated earth-fault protection 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.
• Four-pole systems requiring a full-size neutral conductor.
