1SDA073320R1 ABB E6.2V/f 4000 Ekip G Hi-Touch LSIG 4p WMP Air Circuit Breaker

Why Choose the ABB E6.2V/f 4000 Ekip G Hi-Touch LSIG 4p WMP Air Circuit Breaker?

The ABB E6.2V/f 4000 Ekip G Hi-Touch LSIG 4p WMP, order code 1SDA073320R1, is a high-performance SACE Emax 2 air circuit breaker moving part designed for demanding high-current low-voltage power distribution and generator applications. Part of the ABB Emax 2 E6.2V/f range, this four-pole breaker combines a 4000 A rated current with the advanced Ekip G Hi-Touch LSIG electronic protection release.

The integrated Ekip G Hi-Touch LSIG trip unit provides long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection together with generator-oriented protection functionality. The Hi-Touch platform also supports advanced measurement, monitoring and power-management capabilities, making this configuration particularly suitable for critical generation and industrial distribution systems.

The E6.2V/f 4000 combines the high breaking performance of the V frame with a full-size four-pole configuration. It provides a rated ultimate short-circuit breaking capacity of 150 kA at 415 V AC and 100 kA at 690 V AC, while its withdrawable moving-part construction supports efficient inspection, servicing and replacement within compatible Emax 2 switchgear assemblies.

Advanced Generator and LSIG Protection for Critical Power Distribution

Air circuit breakers such as the ABB Emax 2 E6.2V/f provide switching and protection for major low-voltage distribution and generation circuits. By detecting overload, short-circuit and earth-fault conditions and interrupting the affected circuit, the breaker helps protect switchgear, conductors, generators, transformers and other connected electrical equipment against potentially damaging fault currents.

The Ekip G Hi-Touch LSIG electronic trip unit combines comprehensive LSIG circuit protection with generator-oriented protection and advanced monitoring capabilities. Together with the 4000 A E6.2V/f architecture, breaking capacities of up to 150 kA and withdrawable construction, it provides a robust solution for power-generation plants, critical industrial switchboards and infrastructure systems requiring sophisticated protection and maintainable switchgear.

Typical Applications

• Generator protection and power-generation systems.
• Main incoming protection in high-current low-voltage switchboards.
• Industrial power-distribution systems.
• Transformer secondary and main distribution protection.
• Power plants and critical infrastructure installations.
• High-fault-level switchgear and power distribution assemblies.
