1SDA073286R1 ABB E6.2V 6300 Ekip Touch LSIG 4p WMP Air Circuit Breaker

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

The ABB E6.2V 6300 Ekip Touch LSIG 4p WMP, order code 1SDA073286R1, 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 LSIG electronic trip unit, it provides comprehensive long-time overload, short-time selective short-circuit, instantaneous short-circuit and earth-fault protection.

As part of the ABB Emax 2 E6.2V series, this breaker combines very high current capability with enhanced fault-breaking performance and sophisticated electronic protection. The Ekip Touch release provides an intuitive touchscreen interface for configuring protection settings and accessing operating information, while the LSIG functionality adds integrated earth-fault protection to the standard overload and short-circuit protection functions.

The E6.2V 6300 has a rated uninterrupted current of 6300 A and a rated operational voltage of 690 V AC. Its V performance class provides a rated ultimate short-circuit breaking capacity of 150 kA at 400 V AC, while the withdrawable moving-part configuration enables installation with the appropriate ABB Emax 2 fixed chassis for efficient inspection, maintenance and replacement.

Advanced LSIG Protection for High-Fault-Level Power Distribution

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 and 150 kA short-circuit breaking capacity at 400 V AC makes this breaker particularly suitable for main incomers, transformer secondary circuits, bus couplers and major feeders where prospective fault currents can be exceptionally high.

The Ekip Touch LSIG electronic trip unit provides configurable long-time, short-time, instantaneous and earth-fault protection. This combination enables comprehensive protection and coordination within complex electrical networks, while the touchscreen interface simplifies access to settings and operating information. The withdrawable Emax 2 architecture also supports maintainability in critical installations where service continuity is important.

Typical Applications

• Main incomers in very 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 requiring integrated earth-fault protection.
• Distribution systems with demanding prospective short-circuit levels.
