1SDA072027R1 ABB E6.2V/f 6300 Ekip G Touch LSIG 4p FHR Air Circuit Breaker

Why Choose the ABB E6.2V/f 6300 Ekip G Touch LSIG 4p FHR Air Circuit Breaker?

The ABB E6.2V/f 6300 Ekip G Touch LSIG 4p FHR, order code 1SDA072027R1, is a high-performance SACE Emax 2 air circuit breaker designed for advanced generator and low-voltage power distribution protection. With a 6300 A rated uninterrupted current, four-pole full-size neutral construction and Ekip G Touch LSIG electronic trip unit, it provides comprehensive protection against overloads, short circuits and earth faults in critical high-current installations.

The Ekip G Touch LSIG release combines long-time, short-time, instantaneous and ground-fault protection with generator-oriented protection capabilities. Its advanced electronic platform supports precise protection settings and monitoring, making the breaker particularly suitable for generator switchboards, power plants, industrial facilities and other applications where reliable coordination and continuity of service are essential.

The E6.2V/f performance level provides an ultimate short-circuit breaking capacity of 150 kA at 440 V AC and a rated short-time withstand current of 100 kA for 1 second. This fixed four-pole version has a full-size neutral and rear flat horizontal terminals, providing a robust solution for high-power switchboards with very high prospective fault currents.
