Comprehensive LSIG Protection for Power Distribution
The ABB SACE Emax 2 E2.2B is designed for switching and protection of high-current low-voltage distribution circuits. Its 42 kA breaking and one-second short-time withstand ratings at the specified voltage level provide dependable fault-management capability for switchboards where protection coordination and continuity of supply are important considerations.
The Ekip Dip LSIG release combines four fundamental protection functions in one electronic trip unit. Long-time protection responds to sustained overloads, short-time protection supports selective coordination, instantaneous protection responds rapidly to severe short circuits, and the G function adds earth-fault protection. This makes the 1SDA072333R1 a versatile solution for main distribution and feeder protection applications.
Typical Applications
- Main low-voltage electrical distribution switchboards.
- Industrial power distribution systems.
- Transformer secondary and installation protection.
- Commercial building electrical infrastructure.
- Manufacturing and process plant switchgear.
- Infrastructure power distribution.
- Main incomer and feeder protection.
- Three-phase AC systems requiring comprehensive LSIG protection.
