Why Choose the ABB E1.2B 800 Ekip Hi-Touch LSI 4p WMP Air Circuit Breaker?
The ABB E1.2B 800 Ekip Hi-Touch LSI 4p WMP, order code 1SDA072728R1, is a high-performance four-pole withdrawable air circuit breaker moving part designed for advanced protection and switching in low-voltage electrical distribution systems. As part of the ABB SACE Emax 2 E1.2 series, it combines an 800 A rated current with the sophisticated Ekip Hi-Touch LSI electronic trip unit for precise overload and short-circuit protection.
The Ekip Hi-Touch LSI trip unit provides long-time, short-time and instantaneous protection functions together with advanced measurement, monitoring and power-management capabilities. Its high-level electronic interface supports detailed system supervision and flexible protection configuration, making the breaker well suited to sophisticated industrial, commercial and infrastructure power-distribution applications.
The E1.2B performance level provides an ultimate short-circuit breaking capacity of 42 kA at 440 V AC. Its withdrawable construction enables the moving breaker to be separated from the corresponding fixed chassis for inspection and maintenance, while the four-pole configuration provides switching and protection across four conductors.
