1SDA072641R1 ABB E6.2H 6300 Ekip Dip LI 3P WMP Air Circuit Breaker

Why Choose the ABB 1SDA072641R1 E6.2H 6300 Ekip Dip LI Air Circuit Breaker?

The ABB 1SDA072641R1 is a high-current SACE Emax 2 E6.2H 6300 air circuit breaker moving part designed for protection and switching in demanding low-voltage AC power distribution systems. Configured as an E6.2H 6300 Ekip Dip LI 3p WMP, it combines a 6300 A rated uninterrupted current, three-pole construction and ABB's Ekip Dip electronic trip unit with LI protection functions.

The E6.2H is engineered for major industrial, infrastructure and critical-power distribution systems requiring substantial current-carrying and short-circuit performance. This 6300 A H-performance configuration provides a rated ultimate short-circuit breaking capacity of 100 kA at 440 V AC together with a rated short-time withstand current of 100 kA for 1 s.

The Ekip Dip LI solid-state electronic trip unit provides long-time overload and instantaneous short-circuit protection for straightforward high-current circuit protection. Its three-pole withdrawable moving-part (WMP) architecture is designed for installation with the appropriate Emax 2 fixed part, allowing the breaker to be isolated and withdrawn for inspection, maintenance or replacement.

Reliable LI Protection for 6300 A Power Distribution

Air circuit breakers such as the ABB Emax 2 E6.2H protect major low-voltage electrical networks against overload and short-circuit conditions. With a 6300 A rated uninterrupted current, 100 kA ultimate short-circuit breaking capacity at 440 V AC and 100 kA short-time withstand capability for 1 s, the 1SDA072641R1 is designed for critical distribution positions carrying exceptionally high currents.

The Ekip Dip LI trip unit provides two fundamental electronic protection functions. Long-time protection responds to sustained overload conditions, while instantaneous protection rapidly trips the breaker when severe short-circuit currents occur. Combined with the robust E6.2H frame and withdrawable architecture, this configuration provides dependable protection together with practical maintainability for large high-current switchboards.
