Advanced Generator and Distribution Protection with Ekip G Touch
The ABB Emax 2 E4.2H combines high-current switching capability with the generator-oriented Ekip G Touch LSIG protection platform. Its 4000 A current rating, 100 kA breaking capacity at 400–440 V AC and high short-time withstand capability make it suitable for protecting switchboards, generators, transformers, busbars, cables and other critical components in substantial low-voltage power systems.
The LSIG protection profile combines long-time overload, selective short-time, instantaneous short-circuit and earth-fault protection. Short-time protection assists coordination between upstream and downstream protective devices, while integrated earth-fault protection adds another layer of fault detection. The Ekip G Touch platform makes this configuration particularly relevant where generator and installation protection functions are required alongside comprehensive circuit-breaker protection.
Typical Applications
- Generator protection and generator switchboards.
- Main incomer protection in high-capacity low-voltage switchboards.
- Industrial power generation and distribution systems.
- Transformer secondary protection.
- Data centres and critical-power installations.
- Commercial and infrastructure electrical distribution.
