Why Choose the ABB E1.2B 800 Ekip Hi-Touch LSI 3P F F Air Circuit Breaker?
The ABB E1.2B 800 Ekip Hi-Touch LSI 3P F F, order code 1SDA070748R1, is an 800 A three-pole fixed air circuit breaker from the ABB SACE Emax 2 range. Designed for low-voltage power distribution, it combines the compact E1.2 frame with ABB's advanced Ekip Hi-Touch LSI electronic trip unit for sophisticated protection, measurement and supervision of demanding electrical installations.
The E1.2B performance level provides a rated ultimate short-circuit breaking capacity of 42 kA across its specified AC operating-voltage range. The Ekip Hi-Touch LSI release provides long-time (L), short-time selective (S) and instantaneous (I) protection, allowing overload and short-circuit protection to be coordinated with other protective devices in the distribution network.
Rated at 800 A and up to 690 V AC, the 1SDA070748R1 uses a fixed three-pole configuration with front terminals. Its high-functionality trip unit, compact Emax 2 construction and robust short-circuit performance make it suitable for main distribution, feeder and critical power applications requiring advanced protection and system visibility.
