The ABB E1.2N 800 Ekip Hi-Touch LSIG 4p F F, order code 1SDA071399R1, is an advanced four-pole air circuit breaker (ACB) designed for switching, protection, measurement and monitoring in low-voltage power distribution systems. Part of the ABB SACE Emax 2 series, this fixed circuit breaker combines an 800 A rated current, high short-circuit performance and the sophisticated Ekip Hi-Touch LSIG electronic protection release.
The integrated Ekip Hi-Touch LSIG electronic trip unit provides long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection. The Hi-Touch platform also provides advanced measurement and network analysis capabilities, making this breaker particularly suitable for installations requiring selective coordination, comprehensive fault protection and detailed supervision of electrical system performance.
With a rated operational voltage of 690 V AC and an ultimate short-circuit breaking capacity of 66 kA at 400/415 V AC, the E1.2N 800 provides robust protection in the compact Emax 2 E1.2 frame. This version features a four-pole fixed configuration with front terminals, making it suitable for sophisticated three-phase four-wire switchboards and power distribution assemblies.
Air circuit breakers such as the ABB Emax 2 E1.2N provide switching and protection for low-voltage electrical distribution systems. By detecting overload, short-circuit and earth-fault conditions and interrupting fault current, the breaker helps protect switchboards, cables, busbars and connected electrical equipment while supporting dependable operation and continuity of the wider electrical installation.
The Ekip Hi-Touch LSIG release combines long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection with advanced electrical measurement and network analysis. Short-time protection supports selective coordination between protective devices, while integrated earth-fault protection and Network Analyzer functionality provide enhanced fault protection and detailed supervision of power quality and electrical system performance.
