Advanced LSIG and Ground-Fault Protection for Low-Voltage Distribution
The ABB E2.2S 250 combines the high-performance switching and fault-interruption capabilities of the SACE Emax 2 platform with the advanced protection functionality of the Ekip G Touch LSIG release. Long-time protection responds to sustained overload conditions, short-time protection supports selective coordination, instantaneous protection provides rapid interruption of severe short circuits, and integrated ground-fault protection provides an additional layer of protection against earth-fault conditions.
With an ultimate breaking capacity of 85 kA at 400–440 V AC, service breaking capacity equal to 100% of Icu and a rated short-time withstand current of 66 kA for 1 s, the breaker is designed for demanding distribution systems with substantial prospective fault levels. Its four-pole, withdrawable construction also provides flexibility for switchgear maintenance while supporting applications where the neutral conductor forms part of the protected circuit.
Typical Applications
- Industrial low-voltage switchboards.
- Main incoming and distribution circuit protection.
- Four-pole and four-wire power distribution systems.
- Commercial building electrical distribution.
- Manufacturing and process facilities.
- Infrastructure and critical-power systems.
- Transformer and generator distribution systems.
- Installations requiring comprehensive overload, selective short-circuit, instantaneous and ground-fault protection.
