Why Choose the ABB E6.2H 6300 Ekip Dip LSI 3p F HR Air Circuit Breaker?
The ABB E6.2H 6300 Ekip Dip LSI 3p F HR, order code 1SDA071292R1, is a high-current Emax 2 air circuit breaker (ACB) designed for protection, switching and isolation in demanding low-voltage electrical distribution systems. As part of the ABB SACE Emax 2 series, it combines a substantial 6300 A rated uninterrupted current with the E6.2 frame and H short-circuit performance level for industrial, infrastructure and critical power applications.
This fixed three-pole circuit breaker incorporates the Ekip Dip LSI solid-state electronic trip unit, providing long-time overload, selective short-time and instantaneous short-circuit protection. The LSI protection functions support selective coordination between upstream and downstream protective devices, while the Ekip Dip interface provides straightforward local configuration of the principal protection settings.
With a rated operational voltage of 690 V AC, a rated insulation voltage of 1000 V AC and a rated impulse withstand voltage of 12 kV, the E6.2H 6300 is engineered for demanding high-current distribution. Its fixed three-pole construction and rear horizontal terminals provide a robust solution for integration into large low-voltage switchboards.
