Why Choose the ABB E1.2N 1250 Ekip G Hi-Touch LSIG 3P F F Air Circuit Breaker?
The ABB E1.2N 1250 Ekip G Hi-Touch LSIG 3P F F (1SDA070850R1) is a high-performance three-pole fixed air circuit breaker (ACB) from the ABB SACE Emax 2 range. Designed for demanding low-voltage power distribution and generator applications, it combines a rated uninterrupted current of 1250 A with the high breaking performance of the E1.2N frame and ABB's advanced Ekip G Hi-Touch electronic protection platform.
The integrated Ekip G Hi-Touch LSIG electronic trip unit provides long-time, short-time, instantaneous and ground-fault protection together with advanced generator-oriented protection functionality. This comprehensive protection platform makes the breaker particularly suitable for installations where generators, cables, busbars and critical electrical loads require sophisticated protection, monitoring and coordination.
The E1.2N performance level provides a rated ultimate short-circuit breaking capacity of 66 kA and a rated short-time withstand current of 50 kA. Supplied as a fixed three-pole breaker with front terminals, the 1SDA070850R1 provides a compact solution for permanent installation in industrial, infrastructure and generator switchboards operating at voltages up to 690 V AC.
