Why Choose the ABB E1.2N 1250 Ekip Hi-Touch LSI 3p F F Air Circuit Breaker?
The ABB 1SDA070848R1, designated E1.2N 1250 Ekip Hi-Touch LSI 3p F F, is a SACE Emax 2 air circuit breaker (ACB) designed for advanced protection, switching and supervision of low-voltage AC power distribution systems. Built on the compact ABB SACE Emax 2 E1.2 frame, this fixed three-pole breaker combines a 1250 A rated uninterrupted current with the advanced Ekip Hi-Touch LSI solid-state electronic trip unit.
The Ekip Hi-Touch LSI release provides long-time overload, short-time short-circuit and instantaneous short-circuit protection. The Hi-Touch platform extends conventional circuit protection with advanced measurement and network-analysis functionality, giving operators detailed electrical information alongside configurable protection for sophisticated power-distribution installations.
Rated for operation at 690 V AC, the E1.2N 1250 provides a rated ultimate short-circuit breaking capacity of 66 kA at 400 V AC. Its N performance level, fixed three-pole construction and front terminals make it particularly suitable for industrial, commercial and infrastructure switchboards requiring high fault-breaking capability together with advanced electronic protection and monitoring.

Advanced Protection and Monitoring with Ekip Hi-Touch LSI
The Ekip Hi-Touch LSI trip unit combines three complementary overcurrent protection functions with the advanced capabilities of ABB's Hi-Touch platform. Long-time protection responds to sustained overloads, short-time protection provides a controlled response to short-circuit currents to support selectivity, and instantaneous protection rapidly disconnects severe faults when immediate interruption is required.
Beyond its core protection functions, the Hi-Touch platform is designed for advanced electrical measurement and network analysis. Combined with the 66 kA breaking capability at 400 V AC of the E1.2N frame, this makes the 1SDA070848R1 particularly suitable for distribution systems where high fault-current performance, selective protection and detailed supervision are important requirements.
Typical Applications
- Industrial low-voltage power distribution systems.
- Main and sub-main electrical switchboards.
- Transformer-fed distribution systems.
- Commercial building power distribution.
- Manufacturing and process facilities.
- Infrastructure and critical-power installations requiring advanced LSI protection and monitoring.
