1SDA072458R1 ABB E4.2V 2000 Ekip Hi-Touch LSI 3P WMP Air Circuit Breaker

Why Choose the ABB 1SDA072458R1 E4.2V 2000 Ekip Hi-Touch LSI Air Circuit Breaker?

The ABB 1SDA072458R1 is a high-performance Emax 2 E4.2V 2000 air circuit breaker moving part designed for advanced protection and control of demanding low-voltage power distribution systems. Configured as an E4.2V 2000 Ekip Hi-Touch LSI 3p WMP, it combines a 2000 A rated current, three-pole construction and ABB's advanced Ekip Hi-Touch electronic trip unit with LSI protection functions.

As part of the ABB SACE Emax 2 air circuit breaker series, the E4.2V platform is engineered for installations with high prospective fault currents and demanding requirements for protection, measurement and system integration. The V performance level provides very high short-circuit interruption capability, making the breaker suitable for critical industrial, commercial and infrastructure power-distribution applications.

The Ekip Hi-Touch LSI trip unit provides long-time overload, short-time selective short-circuit and instantaneous short-circuit protection together with advanced measurement, monitoring and protection capabilities. Its three-pole withdrawable moving-part (WMP) configuration is designed for use with the appropriate Emax 2 fixed part, enabling efficient isolation, inspection and servicing in compatible switchboards.

Advanced Protection for Critical Low-Voltage Distribution

Air circuit breakers such as the ABB Emax 2 E4.2V protect high-current low-voltage networks against damaging overload and short-circuit conditions. The E4.2V platform combines substantial current-carrying capability with very high short-circuit performance, making it particularly suitable for main distribution positions and other critical points within electrical networks.

The Ekip Hi-Touch LSI trip unit enhances this protection with advanced electronic functionality. Long-time protection responds to sustained overloads, short-time protection supports selective coordination with downstream protective devices and instantaneous protection provides rapid interruption of severe short circuits. The Hi-Touch platform also provides extensive measurement and monitoring capabilities for sophisticated power-distribution applications.

Typical Applications

• Main incoming protection in high-current low-voltage switchboards.
• Industrial power distribution systems.
• Large commercial building electrical distribution.
• Data centres and critical-power installations.
• Transformer secondary and feeder protection.
• Generator and standby-power distribution.
• Manufacturing and process-industry switchgear.
• Infrastructure systems requiring advanced selective circuit protection.
