Advanced LSI Protection for Withdrawable Power Distribution
Withdrawable air circuit breakers allow the active breaker assembly to be removed from its fixed chassis, supporting inspection, maintenance and replacement while the switchboard's fixed connections remain installed. The ABB Emax 2 E1.2 platform combines this service-friendly architecture with compact construction and robust electrical performance for modern low-voltage distribution systems.
The Ekip Touch LSI electronic release protects against sustained overloads, delayed short-circuit conditions and severe instantaneous faults. Its configurable protection functions help engineers coordinate the breaker with upstream and downstream devices, while the E1.2N frame provides the breaking and short-time withstand capability required for dependable and selective power distribution.
Typical Applications
- Low-voltage main distribution switchboards.
- Transformer and installation protection.
- Generator distribution and protection systems.
- Industrial power distribution networks.
- Commercial building electrical distribution.
- Manufacturing and process plant switchboards.
- Incoming and feeder circuit protection.
- Withdrawable switchgear requiring convenient breaker servicing.
- Distribution networks requiring configurable LSI overcurrent protection.
