Why Choose the ABB E1.2C 630 Ekip Touch LI Air Circuit Breaker?
The ABB E1.2C 630 Ekip Touch LI, order code 1SDA070714R1, 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. These characteristics make the breaker suitable for industrial and commercial distribution systems where reliable interruption of fault currents and coordinated circuit protection are essential.
The fitted Ekip Touch LI solid-state release provides adjustable long-time overload (L) and instantaneous short-circuit (I) protection through ABB's touchscreen-based Ekip platform. The breaker is supplied in a compact fixed configuration with front terminals, four auxiliary contacts and circuit-breaker open/closed position indication for straightforward integration into low-voltage switchboards.
Key Advantages

Ekip Touch LI Protection for Low-Voltage Distribution
The Ekip Touch LI release provides two fundamental protection functions for low-voltage distribution circuits. Long-time protection responds to sustained overload conditions that could otherwise cause excessive heating or damage to cables and equipment, while instantaneous protection provides rapid tripping when a severe short-circuit current exceeds the configured threshold.
Combining these electronic protection functions with the E1.2C breaker's 50 kA breaking capacity at 440 V AC and 42 kA one-second withstand capability provides a robust solution for distribution systems requiring dependable fault interruption. The fixed construction and front-terminal arrangement further simplify integration into compact switchboards where accessibility and efficient use of panel space 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 electronic overload and instantaneous short-circuit protection.
- Fixed switchboard installations requiring a compact 630 A three-pole air circuit breaker.
