1SDA073285R1 ABB E6.2V 6300 Ekip Touch LSI 4p WMP Air Circuit Breaker

Why Choose the ABB E6.2V 6300 Ekip Touch LSI 4p WMP Air Circuit Breaker?

The ABB E6.2V 6300 Ekip Touch LSI 4p WMP, order code 1SDA073285R1, is a high-performance four-pole air circuit breaker moving part from the ABB SACE Emax 2 range, designed for protection, switching and isolation in very high-current low-voltage electrical distribution systems. With a rated current of 6300 A and an advanced Ekip Touch LSI electronic trip unit, it provides configurable long-time overload, short-time selective short-circuit and instantaneous short-circuit protection for demanding industrial, commercial and infrastructure installations.

As part of the ABB Emax 2 E6.2V series, this breaker combines very high current capability with enhanced fault-breaking performance. The Ekip Touch release provides an intuitive touchscreen interface for protection configuration and operating information, while the withdrawable moving-part construction allows the breaker to be used with the appropriate Emax 2 fixed chassis for efficient inspection, servicing and replacement.

The E6.2V 6300 has a rated uninterrupted current of 6300 A, a 690 V AC rated operational voltage and a 1000 V AC rated insulation voltage. Its V performance class provides a rated ultimate short-circuit breaking capacity of up to 150 kA at 400–440 V AC, together with a 100 kA short-time withstand current for 1 s and 3 s, making it suitable for installations with demanding fault levels.

Advanced High-Fault-Level Power Distribution Protection

Air circuit breakers such as the ABB Emax 2 E6.2V provide switching, isolation and electrical protection for high-current low-voltage distribution systems. The combination of a 6300 A current rating, up to 150 kA short-circuit breaking capacity and high short-time withstand capability makes this breaker particularly suitable for main incomers, transformer secondary circuits, bus couplers and major outgoing feeders in large switchboards.

The Ekip Touch LSI electronic trip unit provides configurable long-time, short-time and instantaneous protection, enabling coordination with downstream protective devices. Its touchscreen interface simplifies access to settings and operating information, while the Emax 2 withdrawable architecture supports maintainability in critical installations where high fault performance and continuity of service are important.

Typical Applications

• Main incomers in high-current low-voltage switchboards.
• Industrial power distribution systems.
• Transformer secondary protection.
• Bus couplers and bus-tie circuit breaker applications.
• Data centres and critical power infrastructure.
• Large commercial buildings and infrastructure facilities.
• Manufacturing plants and process industries.
• Utility and energy distribution systems.
• High-current switchgear with demanding prospective fault levels.
