Why Choose the ABB E1.2N 630 Ekip Hi-Touch LSIG Air Circuit Breaker?
The ABB E1.2N 630 Ekip Hi-Touch LSIG, order code 1SDA070729R1, is a high-performance SACE Emax 2 air circuit breaker engineered for protection, control and advanced monitoring in low-voltage power distribution systems. This configuration combines a 630 A rated current, three-pole construction, fixed installation and front terminals with ABB's advanced Ekip Hi-Touch LSIG solid-state electronic protection release.
The E1.2N performance level provides an ultimate short-circuit breaking capacity of 66 kA at 380–440 V AC and 50 kA at 500–690 V AC. Its combination of high breaking performance and compact E1.2 construction makes the breaker suitable for demanding industrial, commercial and critical-power distribution systems.
The fitted Ekip Hi-Touch LSIG release provides adjustable long-time overload, short-time selective short-circuit, instantaneous short-circuit and ground-fault protection. The Hi-Touch platform also provides advanced measurement and power-quality functionality, enabling the breaker to serve as both a protective device and an intelligent monitoring point within modern electrical distribution systems.
