Advanced LSI Protection for Power Distribution
The ABB SACE Emax 2 E1.2C provides a robust switching and protection point within low-voltage power-distribution systems. Its Ekip Touch LSI release combines Long-time overload protection, Short-time delayed short-circuit protection and Instantaneous short-circuit protection. This combination enables protection against sustained overloads and severe faults while the Short-time function supports selective coordination between protective devices.
With a 1250 A current rating, 50 kA ultimate breaking capacity at 440 V AC and 42 kA short-time withstand capability for 1 s, the E1.2C is suited to demanding distribution systems. Its withdrawable construction allows the moving breaker portion to be separated from the corresponding fixed chassis, supporting inspection, servicing and replacement where maintainability and system availability are important.
Typical Applications
- Main and distribution switchboards.
- Industrial low-voltage power distribution systems.
- Commercial building electrical distribution.
- Manufacturing and process-control facilities.
- Data centres and critical-power distribution.
- Infrastructure and utility installations.
- Transformer secondary distribution.
- Four-pole circuits requiring configurable LSI electronic protection and selective coordination.
