1SDA071906R1 ABB E6.2V 5000 Ekip Touch LSIG 4p FHR Air Circuit Breaker

Why Choose the ABB E6.2V 5000 Ekip Touch LSIG 4p FHR Air Circuit Breaker?

The ABB E6.2V 5000 Ekip Touch LSIG 4p FHR, order code 1SDA071906R1, is a high-performance four-pole SACE Emax 2 air circuit breaker designed for protection, switching and supervision in demanding low-voltage power-distribution systems. Part of the ABB SACE Emax 2 E6.2 series, this fixed breaker combines a 5000 A rated uninterrupted current with the advanced Ekip Touch LSIG solid-state electronic trip unit.

The E6.2V performance level delivers exceptional short-circuit performance, providing a rated ultimate short-circuit breaking capacity of 150 kA at 400/415/440 V AC, 130 kA at 500/525 V AC and 100 kA at 690 V AC. Its Ekip Touch LSIG release provides long-time overload, selective short-time, instantaneous short-circuit and earth-fault protection, supporting comprehensive protection and selective coordination across high-capacity distribution networks.

This model is a fixed four-pole air circuit breaker equipped with rear flat horizontal (FHR) terminals. With a rated voltage of 690 V, 100 kA short-time withstand current for both 1 s and 3 s, four auxiliary contacts and breaker open/closed position indication, the 1SDA071906R1 provides a robust solution for major switchboards and critical high-current distribution systems.
