Why Choose the ABB 1SDA078458R1 E4.2S-A 2500 Ekip Dip LI 3-Pole Air Circuit Breaker?
The ABB 1SDA078458R1 is an E4.2S-A 2500 Ekip Dip LI 3-pole air circuit breaker moving part from the ABB SACE Emax 2 range. Designed for demanding low-voltage power distribution applications, it combines the E4.2 frame with a 2500 A frame rating and ABB's Ekip Dip LI electronic trip unit.
The Ekip Dip LI trip unit provides electronic long-time overload and instantaneous short-circuit protection. This streamlined protection configuration makes the 1SDA078458R1 suitable for installations requiring dependable electronic protection without the additional short-time or earth-fault functions provided by more advanced Ekip configurations.
This model has a 3-pole configuration and is supplied as the moving part of a drawout circuit breaker (WMP). The E4.2S-A performance class provides a 65 kA interrupting rating and 65 kA withstand rating, making it a robust solution for industrial, commercial and infrastructure distribution systems.

Ekip Dip LI Electronic Protection
The ABB Ekip Dip LI trip unit provides two principal electronic protection functions. The L function provides long-time protection against sustained overload conditions, while the I function provides instantaneous protection against high short-circuit currents, allowing rapid breaker operation when severe faults occur.
Combined with the Emax 2 E4.2S-A 2500 A platform, the Ekip Dip LI trip unit provides a practical protection solution for high-current low-voltage distribution systems. The drawout moving-part construction also supports switchgear designs where breaker removal, inspection and maintenance flexibility are important.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial power distribution systems.
- Commercial building electrical infrastructure.
- Manufacturing and process facilities.
- Drawout switchgear requiring electronic LI protection.
- Three-phase installations requiring a 2500 A Emax 2 breaker moving part.
