1SDA073110R1 ABB E4.2V 2500 Ekip G Hi-Touch LSIG 4P Air Circuit Breaker

Why Choose the ABB 1SDA073110R1 E4.2V 2500 Ekip G Hi-Touch LSIG Air Circuit Breaker?

The ABB 1SDA073110R1 is a high-performance SACE Emax 2 E4.2V air circuit breaker moving part engineered for advanced generator and low-voltage power-distribution protection. This four-pole withdrawable unit has a rated uninterrupted current of 2500 A and incorporates ABB's Ekip G Hi-Touch LSIG solid-state electronic trip unit, providing long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection.

The Ekip G Hi-Touch release is specifically suited to demanding generator applications and combines configurable LSIG protection with advanced measurement and power-quality monitoring. Integrated Ekip Measuring Pro and Network Analyzer functionality provides enhanced electrical supervision, while the touch-screen interface supports intuitive configuration and access to operating information.

With a rated operational voltage of 690 V AC, an ultimate short-circuit breaking capacity of 150 kA at 380–440 V AC and 100 kA at 500–690 V AC, the E4.2V 2500 is designed for systems with exceptionally high prospective fault currents. Its four-pole configuration, generator-specific protection capabilities and withdrawable moving-part construction make it a strong choice for critical generation and high-capacity distribution installations.

Advanced Generator and High-Fault-Level Distribution Protection

The ABB SACE Emax 2 E4.2V combines high-current switching with sophisticated electronic protection for generator and critical distribution systems. Its Ekip G Hi-Touch LSIG release provides adjustable overload, selective short-circuit, instantaneous and ground-fault protection while incorporating generator-specific protection functions, advanced electrical measurement and real-time power-quality analysis.

The E4.2V platform is engineered for installations with exceptionally high prospective fault currents. Breaking capacities of up to 150 kA at 380–440 V AC provide robust fault interruption, while the withdrawable architecture allows the moving part to be separated from its corresponding fixed chassis for inspection, servicing or replacement.

Typical Applications

• Generator protection and power-generation switchboards.
• Main incoming protection for high-capacity low-voltage switchboards.
• Industrial power-distribution systems with very high prospective fault levels.
• Critical infrastructure and commercial electrical distribution.
• Transformer secondary and installation protection.
• High-current feeders requiring advanced LSIG protection, measurement and power-quality monitoring.
