Why Choose the ABB 1SDA071923R1 Emax 2 Air Circuit Breaker?

The ABB 1SDA071923R1 is a high-current SACE Emax 2 E6.2H air circuit breaker engineered for protection and switching in demanding low-voltage power distribution systems. Configured as an E6.2H 6300 Ekip Dip LSIG 4p FHR, it combines a rated uninterrupted current of 6300 A with ABB's Ekip Dip LSIG solid-state electronic trip unit.

This four-pole fixed circuit breaker provides comprehensive LSIG protection functions, covering long-time overload, short-time delayed short-circuit, instantaneous short-circuit and earth-fault protection. The Ekip Dip release provides configurable electronic protection for very high-current distribution systems requiring dependable fault protection, selective coordination and integrated earth-fault protection.

The E6.2H performance level provides a rated ultimate short-circuit breaking capacity of 100 kA across 400–690 V AC, with a rated service short-circuit breaking capacity equal to 100% of Icu and a rated short-time withstand current of 100 kA for 1 s and 3 s. Its fixed four-pole construction features rear flat horizontal terminals and four change-over auxiliary contacts for integration into high-capacity switchboards.
