Why Choose the ABB E1.2C 1250 Ekip Hi-Touch LSI 3P F F Air Circuit Breaker?
The ABB E1.2C 1250 Ekip Hi-Touch LSI 3P F F (1SDA070838R1) is a high-performance three-pole fixed air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for protection, switching and isolation in demanding low-voltage power distribution systems. Built around the compact E1.2 frame, this configuration provides a rated uninterrupted current of 1250 A and combines strong short-circuit performance with ABB's advanced electronic protection technology.
The breaker incorporates an Ekip Hi-Touch LSI electronic trip unit, providing long-time, short-time and instantaneous protection. The Hi-Touch platform is designed for applications requiring advanced protection, measurement and power-management functionality, while the LSI protection package helps safeguard cables, busbars and connected equipment against overload and short-circuit conditions.
The E1.2C performance level provides a rated ultimate short-circuit breaking capacity of 50 kA at 440 V AC together with a rated short-time withstand current of 42 kA for 1 s. Supplied in a fixed three-pole configuration with front connections, the 1SDA070838R1 provides a compact and capable solution for industrial, commercial and infrastructure low-voltage switchboards.
