1SDA070834R1 ABB E1.2C 1250 Ekip Touch LI 3p F F Air Circuit Breaker

Why Choose the ABB E1.2C 1250 Ekip Touch LI 3p F F Air Circuit Breaker?

The ABB 1SDA070834R1, designated E1.2C 1250 Ekip Touch LI 3p F F, is a SACE Emax 2 air circuit breaker (ACB) designed for protection and switching in 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 Ekip Touch LI solid-state electronic trip unit.

The Ekip Touch LI release provides long-time overload and instantaneous short-circuit protection. Its touchscreen interface provides intuitive access to protection settings and operating information, combining essential LI protection with the advanced user interface and expandability of ABB's Ekip Touch platform.

Rated for operation up to 690 V AC, the E1.2C 1250 belongs to ABB's 50 kA E1.2C performance class. Its fixed three-pole construction, front terminals and compact E1.2 format make it suitable for industrial, commercial and infrastructure switchboards requiring dependable high-current protection and straightforward electronic configuration.

Electronic Protection with Ekip Touch LI

The Ekip Touch LI electronic trip unit provides two fundamental protection functions for low-voltage distribution circuits. Long-time protection responds to sustained overload conditions that could cause excessive thermal stress, while instantaneous protection rapidly interrupts severe short-circuit currents to limit the electrical and mechanical stresses imposed on the installation.

Unlike the simpler Ekip Dip platform, Ekip Touch provides a touchscreen-based interface for interacting with the trip unit and accessing protection information. Combined with the modular Emax 2 architecture, this gives the 1SDA070834R1 a flexible foundation for installations requiring dependable LI protection together with the usability and expansion possibilities of ABB's Ekip Touch system.

Typical Applications

• Industrial low-voltage power distribution systems.
• Main and sub-main electrical switchboards.
• Transformer and installation protection.
• Commercial building power distribution.
• Manufacturing and process facilities.
• Infrastructure and critical-power distribution systems.
