Why Choose the ABB 1SDA072457R1 E4.2V 2000 Ekip G Touch LSIG Air Circuit Breaker?

The ABB 1SDA072457R1 is a high-performance Emax 2 E4.2V 2000 air circuit breaker moving part designed for protection and control of demanding low-voltage power distribution systems. Configured as an E4.2V 2000 Ekip G Touch LSIG 3p WMP, it combines a 2000 A rated current, three-pole construction and ABB's advanced Ekip G Touch electronic trip unit with comprehensive LSIG protection.

As part of the ABB SACE Emax 2 air circuit breaker series, the E4.2V is engineered for installations requiring exceptionally high short-circuit performance. The V performance level provides an ultimate short-circuit breaking capacity of 150 kA at 415 V AC and 100 kA at 690 V AC, making this breaker suitable for critical industrial and infrastructure distribution systems with high prospective fault currents.

The Ekip G Touch LSIG release provides long-time, short-time, instantaneous and earth-fault protection together with generator-oriented protection functionality. Its withdrawable moving-part (WMP) construction is designed for use with the appropriate Emax 2 fixed part, enabling efficient isolation, inspection and maintenance within compatible withdrawable switchboards.

Key Advantages

  • High-performance ABB Emax 2 E4.2V air circuit breaker moving part.
  • 2000 A rated current for high-current low-voltage distribution systems.
  • Exceptional 150 kA breaking capacity at 415 V AC.
  • Ekip G Touch LSIG electronic trip unit with advanced protection and measurement functionality.
  • Integrated long-time, short-time, instantaneous and earth-fault protection.
  • Ekip G functionality is suited to generator protection and power-generation applications.
  • Three-pole withdrawable configuration supports maintainable switchboard designs.

Advanced Protection for Generator and High-Fault-Level Power Systems

Air circuit breakers such as the ABB Emax 2 E4.2V protect high-current low-voltage networks by detecting abnormal electrical conditions and interrupting fault currents before they can cause serious damage to equipment or distribution infrastructure. The V performance level is particularly suited to systems with very high prospective short-circuit currents, providing breaking capacity up to 150 kA at 415 V AC.

The Ekip G Touch LSIG trip unit extends this capability with advanced electronic protection suitable for generator and power-distribution applications. Long-time protection responds to sustained overloads, short-time protection assists with selective coordination, instantaneous protection responds rapidly to severe short circuits and earth-fault protection detects current flowing through unintended earth paths.

Typical Applications

  • Generator protection and power-generation systems.
  • Main incoming protection in high-fault-level low-voltage switchboards.
  • Industrial power distribution systems.
  • Critical infrastructure and utility installations.
  • Large commercial and data-centre power distribution.
  • Transformer secondary and high-current feeder protection.
  • Manufacturing and process-industry switchgear.
  • Withdrawable switchboards requiring advanced LSIG protection.
