Why Choose the ABB E1.2N 630 Ekip Touch LSI 3P F F Air Circuit Breaker?
The ABB E1.2N 630 Ekip Touch LSI 3P F F, order code 1SDA070725R1, is a 630 A three-pole fixed air circuit breaker from the ABB SACE Emax 2 range. Designed for low-voltage AC power distribution, it combines the compact E1.2 frame with an advanced Ekip Touch LSI electronic trip unit for overload, selective short-circuit and instantaneous short-circuit protection.
The E1.2N performance level provides a rated ultimate short-circuit breaking capacity of 66 kA at common low-voltage distribution levels. Its Ekip Touch LSI release incorporates long-time (L), short-time selective (S) and instantaneous (I) protection functions, supporting coordinated protection strategies where discrimination between upstream and downstream devices is important.
Rated at 630 A and 690 V AC, the 1SDA070725R1 uses a fixed three-pole configuration with front terminals. The breaker is supplied complete with its protection unit, four auxiliary changeover contacts and open/closed position indication, providing a capable solution for industrial, commercial and infrastructure switchboards.

Advanced LSI Protection for Selective Distribution
The Ekip Touch LSI trip unit provides three complementary protection functions. Long-time protection responds to sustained overload currents, short-time protection allows controlled delayed operation during short-circuit conditions to support selectivity, and instantaneous protection provides rapid interruption when severe fault currents occur.
This combination makes the 1SDA070725R1 particularly useful in distribution systems where coordination between protective devices is required. Together with the 630 A rating, E1.2N fault performance and compact fixed construction, the breaker provides a flexible solution for protecting main distribution and feeder circuits while supporting continuity of supply in properly coordinated systems.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial power distribution systems.
- Commercial building electrical distribution.
- Main incomer and feeder protection.
- Selective and coordinated distribution networks.
- Manufacturing and process plant switchgear.
- Motor control centres and power distribution panels.
- Infrastructure and utility electrical installations.
