Why Choose the ABB 1SDA074205R1 Ekip LCD LSI Trip Unit?
The ABB 1SDA074205R1 is a genuine Ekip LCD LSI electronic trip unit supplied for compatible ABB SACE Emax 2 air circuit breakers from E1.2 through E6.2. It combines an LCD user interface with LSI protection functions, providing long-time overload, short-time short-circuit and instantaneous short-circuit protection for low-voltage power distribution applications.
As part of the ABB Ekip protection platform, the Ekip LCD LSI provides electronic protection for installations requiring greater selectivity and protection flexibility than an LI-only release. The LSI configuration combines long-time (L), short-time (S) and instantaneous (I) protection functions to respond to different overload and short-circuit conditions within an electrical distribution system.
The 1SDA074205R1 is specified for the ABB SACE Emax 2 E1.2 through E6.2 range and is supplied as a loose Ekip electrical trip unit. ABB identifies this version for both IEC and UL applications, making it a versatile replacement or configuration component for compatible Emax 2 circuit breaker installations.
Key Advantages

LSI Electronic Protection for ABB SACE Emax 2
Electronic trip units monitor circuit conditions and initiate circuit breaker tripping when configured protection thresholds are exceeded. An LSI protection configuration combines long-time protection for sustained overloads, short-time protection for short-circuit conditions where time-selective coordination may be required, and instantaneous protection for severe short-circuit currents requiring rapid interruption.
The ABB Ekip LCD LSI brings these three core protection functions together in a dedicated electronic release for compatible SACE Emax 2 circuit breakers. Compared with an LI release, the additional short-time protection function provides another level of protection coordination, while the LCD interface supports convenient local interaction with the trip unit.
Typical Applications
- ABB SACE Emax 2 E1.2 through E6.2 air circuit breaker installations.
- Low-voltage main distribution switchboards.
- Industrial electrical distribution systems.
- Manufacturing and process plant switchgear.
- Commercial building power distribution.
- Infrastructure and critical power distribution systems.
- Applications requiring coordinated long-time, short-time and instantaneous protection.
