1SDA072598R1 ABB E6.2V 4000 Ekip Hi-Touch LSI 3p WMP Air Circuit Breaker

Why Choose the ABB E6.2V 4000 Ekip Hi-Touch LSI 3p WMP Air Circuit Breaker?

The ABB 1SDA072598R1 is a high-performance SACE Emax 2 E6.2V air circuit breaker (ACB) designed for advanced protection, measurement and control of demanding low-voltage electrical distribution systems. Rated at 4000 A, this three-pole breaker combines ABB’s high-breaking-capacity E6.2V frame with an advanced Ekip Hi-Touch LSI electronic trip unit.

As part of the ABB SACE Emax 2 air circuit breaker series, the E6.2V is engineered for high-current industrial switchboards, data centres, infrastructure, commercial installations and critical power distribution. The Ekip Hi-Touch electronic release provides sophisticated protection and monitoring capabilities, while its LSI functions provide long-time overload, short-time selective and instantaneous short-circuit protection.

The 1SDA072598R1 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 E6.2V performance level provides an ultimate short-circuit breaking capacity of 150 kA at 400–440 V AC, 130 kA at 500 V AC and 100 kA at 690 V AC, together with a rated short-time withstand current of 100 kA for 1 second.

Advanced Circuit Protection and Power Management

Air circuit breakers such as the ABB SACE Emax 2 protect high-current low-voltage electrical systems against overloads and short circuits. The E6.2V performance level combines a 4000 A current rating with exceptional short-circuit interruption capability, making this breaker particularly suitable for installations where prospective fault currents are extremely high.

The Ekip Hi-Touch electronic trip unit extends conventional circuit protection with advanced measurement, monitoring and protection functionality. Its LSI functions provide long-time overload, short-time selective and instantaneous short-circuit protection, while the wider Emax 2 architecture supports integration into modern automation, supervision and energy-management systems.

Typical Applications

• Main incoming protection for high-current low-voltage switchboards.
• Industrial power distribution systems.
• Transformer secondary protection and distribution.
• Data centres and high-availability electrical infrastructure.
• Critical power distribution installations.
• Large commercial and infrastructure projects.
• Manufacturing plants and process facilities.
• Systems with exceptionally high prospective short-circuit currents.
