Why Choose the ABB E1.2C 630 Ekip Hi-Touch LSIG 3P F F Air Circuit Breaker?
The ABB E1.2C 630 Ekip Hi-Touch LSIG 3P F F (1SDA070719R1) is an advanced three-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for protection, switching and isolation in demanding low-voltage power distribution systems. Its compact E1.2 frame combines a rated uninterrupted current of 630 A with the high-performance E1.2C breaking-capacity level.
At the heart of the breaker is the Ekip Hi-Touch LSIG electronic trip unit, providing long-time, short-time, instantaneous and earth-fault protection. The addition of ground-fault protection makes this LSIG configuration particularly suitable for installations requiring comprehensive electronic protection against overloads, short circuits and earth faults.
The E1.2C performance level provides a rated ultimate short-circuit breaking capacity of 50 kA at 440 V AC and a rated short-time withstand current of 42 kA for 1 s. This model is a fixed, three-pole breaker with front connections, providing a robust solution for industrial, commercial and infrastructure switchboards where advanced protection and dependable fault interruption are essential.

Advanced LSIG Protection for Low-Voltage Power Distribution
The Ekip Hi-Touch LSIG trip unit provides four complementary protection functions within one intelligent electronic protection system. Long-time protection responds to sustained overloads, short-time protection provides controlled response to high fault currents, instantaneous protection enables rapid interruption of severe short circuits, and ground-fault protection detects potentially damaging current flowing to earth.
Combining LSIG protection with the E1.2C breaker's 50 kA Icu at 440 V AC and 42 kA 1-second short-time withstand capability makes the 1SDA070719R1 well suited to sophisticated distribution systems where fault protection, selectivity and continuity of service are important design considerations. Its fixed construction and front connections also provide a practical arrangement for permanent installation within compatible low-voltage switchboards.
Typical Applications
- Industrial low-voltage switchboards.
- Main and sub-main power distribution systems.
- Feeder and distribution circuit protection.
- Manufacturing and process industry electrical systems.
- Commercial buildings and critical infrastructure.
- Power distribution systems requiring integrated earth-fault protection.
