The ABB E1.2C 630 Ekip Hi-Touch LSI 3P F F (1SDA070718R1) is an advanced three-pole air circuit breaker (ACB) designed for protection, switching and isolation in demanding low-voltage electrical distribution systems. As part of the ABB SACE Emax 2 E1.2 range, it combines a compact fixed-frame design with the sophisticated Ekip Hi-Touch electronic trip unit for precise protection and power distribution management.
The integrated Ekip Hi-Touch LSI electronic release provides long-time, short-time and instantaneous overcurrent protection. This combination protects against overload and short-circuit conditions while offering the adjustable protection functionality required for effective coordination and selectivity in sophisticated industrial and commercial distribution networks.
With a rated uninterrupted current of 630 A, a rated operational voltage up to 690 V AC and a three-pole fixed configuration, the E1.2C 630 provides substantial performance from a compact E1.2 frame. The C performance level delivers a rated ultimate short-circuit breaking capacity of 50 kA at 440 V AC, while front terminals simplify integration into compatible low-voltage switchboards.
Air circuit breakers such as the ABB SACE Emax 2 provide switching, isolation and electronic protection for important low-voltage distribution circuits. The Ekip Hi-Touch trip unit continuously evaluates electrical conditions and operates the breaker according to configured protection thresholds, helping protect cables, busbars and connected equipment against damaging overload and short-circuit conditions.
The LSI protection configuration combines long-time overload protection with short-time and instantaneous short-circuit protection. Together with the E1.2C breaker’s 50 kA breaking capacity at 440 V AC, this provides a powerful protection platform for applications requiring dependable fault interruption, protection coordination and continuity of electrical service.
