1SDA071926R1 ABB E6.2H 6300 Ekip Touch LSIG 4p FHR Air Circuit Breaker

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

The ABB 1SDA071926R1 is a high-capacity Emax 2 air circuit breaker (ACB) designed for protection, switching and control in demanding low-voltage power-distribution systems. Identified as the E6.2H 6300 Ekip Touch LSIG 4p FHR, this four-pole fixed circuit breaker combines a substantial 6300 A rated current with ABB’s advanced Ekip Touch LSIG solid-state electronic trip unit.

As part of the ABB SACE Emax 2 E6.2H series, this breaker provides high short-circuit performance for critical industrial and infrastructure installations. The Ekip Touch LSIG release provides long-time overload, short-time selective short-circuit, instantaneous short-circuit and earth-fault protection, while its touch interface supports convenient configuration and access to protection and operating information.

With a rated voltage of 690 V AC and a breaking capacity of 100 kA, the 1SDA071926R1 is engineered for very high-current distribution systems requiring dependable fault interruption. Its four-pole fixed construction, rear flat horizontal terminals and integrated auxiliary contacts provide a robust configuration for permanent installation in high-capacity low-voltage switchboards.
