1SDA072582R1 ABB E6.2H 4000 Ekip Dip LSI 3p WMP Air Circuit Breaker

Why Choose the ABB E6.2H 4000 Ekip Dip LSI 3p WMP Air Circuit Breaker?

The ABB 1SDA072582R1 is a high-performance SACE Emax 2 E6.2H air circuit breaker (ACB) designed for reliable protection of demanding low-voltage electrical distribution systems. Rated at 4000 A, this three-pole breaker combines ABB’s high-capacity E6.2H frame with an Ekip Dip LSI electronic trip unit providing long-time, short-time and instantaneous protection.

As part of the advanced ABB SACE Emax 2 air circuit breaker series, the E6.2H is engineered for high-current industrial switchboards, infrastructure, data centres, commercial installations and critical power distribution. Its Ekip Dip electronic release provides adjustable protection functions for effective coordination with downstream equipment while maintaining straightforward operation and configuration.

The 1SDA072582R1 is a three-pole withdrawable mobile part (WMP) with a rated uninterrupted current of 4000 A and rated operational voltage of 690 V AC. The E6.2H performance level provides an ultimate short-circuit breaking capacity of 100 kA across key industrial voltages up to 690 V AC and a rated short-time withstand current of 100 kA for 1 second, making it suitable for installations with exceptionally high prospective fault currents.
