Why Choose the ABB E1.2C 800 Ekip Dip LSI Air Circuit Breaker?
The ABB E1.2C 800 Ekip Dip LSI, order code 1SDA070752R1, is a SACE Emax 2 air circuit breaker engineered for dependable protection and control in low-voltage power distribution systems. This configuration combines an 800 A rated current, three-pole construction, fixed installation and front terminals with ABB's Ekip Dip LSI solid-state electronic protection release.
The E1.2C performance level provides an ultimate short-circuit breaking capacity of 50 kA at 400–440 V AC and 42 kA at 500–690 V AC. Its rated short-time withstand current is 42 kA for 1 s, supporting coordinated protection in industrial, commercial and infrastructure distribution systems.
The fitted Ekip Dip LSI release provides long-time overload, short-time selective short-circuit and instantaneous short-circuit protection. Together with the compact E1.2 frame, fixed construction and front-terminal arrangement, this makes the 1SDA070752R1 a practical solution for switchboards requiring reliable electronic protection and selective coordination without the advanced touchscreen functions of higher-tier Ekip releases.

Ekip Dip LSI Protection and Selective Coordination
The Ekip Dip LSI release combines three complementary protection functions. Long-time protection responds to sustained overload conditions, short-time protection provides a controlled response to short circuits to support selective coordination with downstream devices, and instantaneous protection rapidly disconnects severe high-current faults.
The E1.2C's 42 kA one-second short-time withstand capability complements the selective short-time protection function by allowing properly coordinated downstream protective devices time to clear appropriate faults. This combination makes the 1SDA070752R1 well suited to multi-level distribution systems where both dependable fault interruption and continuity of unaffected circuits are important.
Typical Applications
- Low-voltage main and sub-distribution switchboards.
- Industrial power distribution systems.
- Manufacturing and process plant electrical systems.
- Commercial building power distribution.
- Infrastructure and utility installations.
- Generator and transformer distribution assemblies.
- Applications requiring selective LSI electronic protection.
- Fixed switchboard installations requiring an 800 A three-pole air circuit breaker.
