1SDA071930R1 ABB E6.2H 6300 Ekip G Hi-Touch LSIG 4p FHR Air Circuit Breaker

Why Choose the ABB E6.2H 6300 Ekip G Hi-Touch LSIG 4p FHR Air Circuit Breaker?

The ABB E6.2H 6300 Ekip G Hi-Touch LSIG 4p FHR, order code 1SDA071930R1, is a high-performance four-pole SACE Emax 2 air circuit breaker engineered for generator protection and demanding low-voltage power-distribution systems. Part of the ABB SACE Emax 2 E6.2 series, this fixed breaker combines a 6300 A rated uninterrupted current with the advanced Ekip G Hi-Touch LSIG electronic trip unit.

The E6.2H performance level provides a rated ultimate short-circuit breaking capacity of 100 kA at 440 V AC and a rated short-time withstand current of 100 kA for 1 s. Its Ekip G Hi-Touch LSIG release combines long-time overload, selective short-time, instantaneous short-circuit and earth-fault protection with generator-oriented protection and advanced monitoring capabilities.

This version is a four-pole fixed air circuit breaker with rear flat horizontal (FHR) terminals. Rated for operation up to 690 V AC, the 1SDA071930R1 combines very high current-carrying capability, comprehensive generator-oriented protection and sophisticated Ekip functionality for generator switchboards, industrial plants, data centres and other critical high-capacity electrical systems.
