Why Choose the ABB E1.2C 630 Ekip Touch LSI Air Circuit Breaker?
The ABB E1.2C 630 Ekip Touch LSI, order code 1SDA070715R1, is a SACE Emax 2 air circuit breaker designed for dependable protection and control of low-voltage power distribution systems. This configuration combines a 630 A rated uninterrupted current, three-pole construction, fixed installation and front terminals with ABB's advanced Ekip Touch electronic protection release.
The E1.2C performance level provides an ultimate short-circuit breaking capacity of 50 kA at 440 V AC together with a rated short-time withstand current of 42 kA for 1 s. This combination provides robust fault interruption and short-time withstand performance for industrial, commercial and infrastructure distribution systems where protection coordination and continuity are important.
The fitted Ekip Touch LSI solid-state release provides adjustable long-time overload (L), short-time selective short-circuit (S) and instantaneous short-circuit (I) protection. The short-time function adds greater selectivity than an LI-only release, helping downstream protective devices clear appropriate faults before the upstream Emax 2 breaker operates.
Key Advantages
- 630 A rated uninterrupted current for substantial low-voltage distribution circuits.
- 50 kA ultimate short-circuit breaking capacity at 440 V AC.
- 42 kA short-time withstand current for 1 s supports selective protection strategies.
- Advanced Ekip Touch LSI electronic protection release.
- Long-time, short-time and instantaneous protection for coordinated circuit protection.
- Three-pole configuration for three-phase power distribution.
- Fixed construction with front terminals for straightforward switchboard integration.
- Compact E1.2 frame helps optimise valuable switchboard space.

Ekip Touch LSI Protection and Selective Coordination
The Ekip Touch LSI release provides three complementary protection functions. Long-time protection responds to sustained overloads, short-time protection provides an adjustable response to short-circuit conditions for improved selectivity, and instantaneous protection rapidly interrupts severe faults when current exceeds the configured threshold.
The short-time protection function is particularly valuable in multi-level distribution systems because it can help coordinate the E1.2C with downstream protective devices. Combined with the breaker's 42 kA one-second short-time withstand capability, this allows properly engineered systems to maintain selective operation while still providing dependable protection against high fault currents.
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 circuit protection.
- Fixed switchboard installations requiring a compact 630 A three-pole air circuit breaker.
