Why Choose the ABB E1.2N 630 Ekip Touch LI 3P F F Air Circuit Breaker?
The ABB E1.2N 630 Ekip Touch LI 3P F F, order code 1SDA070724R1, is a 630 A three-pole fixed air circuit breaker from the ABB SACE Emax 2 range. Designed for low-voltage power distribution, it combines the compact E1.2 frame with an advanced Ekip Touch LI electronic trip unit for dependable overload and instantaneous short-circuit protection.
The E1.2N performance level provides a rated ultimate short-circuit breaking capacity of 66 kA at 400 V AC. The Ekip Touch LI release provides long-time (L) overload protection together with instantaneous (I) short-circuit protection, making the breaker suitable for distribution circuits where reliable electronic protection and high fault-interruption capability are required.
With a rated uninterrupted current of 630 A, rated voltage of 690 V AC and three-pole fixed construction, the 1SDA070724R1 is engineered for permanent installation in low-voltage switchboards. The complete breaker includes its protection unit, auxiliary changeover contacts and switched-off indication, while an optional motor drive can support electrically operated applications.

Reliable Electronic Protection for Low-Voltage Distribution
The Ekip Touch LI trip unit provides the core protection functions required for many power-distribution circuits. Long-time protection responds to sustained overload currents that could cause damaging thermal stress, while instantaneous protection rapidly trips the circuit breaker when severe short-circuit currents occur.
Combined with the E1.2N frame's 66 kA breaking capacity at 400 V AC, the Ekip Touch release makes the 1SDA070724R1 a capable solution for incoming and feeder protection. Its 630 A rating, fixed construction and compact Emax 2 architecture support efficient integration into industrial, commercial and infrastructure switchboards.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial power distribution systems.
- Commercial building electrical distribution.
- Main incomer and feeder protection.
- Manufacturing and process plant switchgear.
- Motor control centres and power distribution panels.
- Infrastructure and utility electrical installations.
- Fixed switchboards requiring electronic overload and short-circuit protection.
