Why Choose the ABB E1.2B 800 Ekip Hi-Touch LSIG 3P F F Air Circuit Breaker?
The ABB E1.2B 800 Ekip Hi-Touch LSIG 3P F F, order code 1SDA070749R1, is an 800 A three-pole fixed air circuit breaker from the ABB SACE Emax 2 range. It combines the compact E1.2 frame with ABB's advanced Ekip Hi-Touch LSIG solid-state electronic trip unit, providing comprehensive protection for demanding low-voltage power distribution systems.
The E1.2B performance level provides a rated ultimate short-circuit breaking capacity of 42 kA at 400 V AC. Its Ekip Hi-Touch LSIG release incorporates long-time (L), short-time selective (S), instantaneous (I) and ground-fault (G) protection, giving the breaker comprehensive protection against overloads, phase short circuits and earth faults.
Rated at 800 A and 690 V AC, this model uses a fixed three-pole construction with front terminals. It is supplied as a complete device with its protection unit, four auxiliary changeover contacts and circuit-breaker open/closed position indication, making it well suited to industrial, commercial and infrastructure distribution switchboards.

Comprehensive LSIG Protection for Critical Distribution Systems
The Ekip Hi-Touch LSIG release provides a comprehensive protection package for sophisticated low-voltage networks. Long-time protection responds to sustained overloads, short-time selective protection supports coordination between upstream and downstream devices, and instantaneous protection provides rapid interruption of severe short-circuit currents.
The additional ground-fault (G) protection enables the breaker to respond to earth-fault conditions as part of the overall protection strategy. Combined with the E1.2B frame, 800 A current rating and 42 kA short-circuit performance, this makes the 1SDA070749R1 particularly suitable for main distribution and critical feeder applications requiring advanced electronic protection.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial power distribution systems.
- Commercial building electrical distribution.
- Main incomer and feeder protection.
- Selective and coordinated distribution networks.
- Systems requiring integrated ground-fault protection.
- Manufacturing and process plant switchgear.
- Critical-power and infrastructure installations.
