1SDA071020R1 ABB E2.2H 1600 Ekip G Hi-Touch LSIG 3p F HR Air Circuit Breaker

Why Choose the ABB E2.2H 1600 Ekip G Hi-Touch LSIG 3p F HR Air Circuit Breaker?

The ABB 1SDA071020R1, designated E2.2H 1600 Ekip G Hi-Touch LSIG 3p F HR, is a high-performance three-pole air circuit breaker (ACB) designed for advanced protection, monitoring and control in demanding low-voltage power distribution and generator applications. As part of the ABB SACE Emax 2 series, it combines a 1600 A rated uninterrupted current with the sophisticated Ekip G Hi-Touch LSIG electronic trip unit.

The E2.2H is engineered for industrial, infrastructure, critical-power and generation installations where very high short-circuit performance and advanced generator-oriented protection are required. Its Ekip G Hi-Touch LSIG release provides long-time overload (L), short-time selective short-circuit (S), instantaneous short-circuit (I) and earth-fault (G) protection, together with generator-specific protection, advanced measurement and power-quality analysis functionality.

With a rated operational voltage of 690 V AC and rated ultimate short-circuit breaking capacity of 100 kA at 380–440 V AC, the 1SDA071020R1 provides robust protection for high-fault-level electrical networks. This version is a fixed, three-pole circuit breaker with horizontal rear terminals and is supplied with four auxiliary contacts and circuit-breaker open/closed position indication.

Advanced Generator and High-Fault-Level Power Protection

Air circuit breakers such as the ABB SACE Emax 2 E2.2H provide switching, isolation and protection for high-current low-voltage electrical systems. With a 1600 A current rating, 100 kA ultimate breaking capacity at 380–440 V AC and 85 kA short-time withstand current for 1 s, this high-performance configuration is particularly suited to electrical networks with substantial prospective fault currents and demanding selectivity requirements.

The Ekip G Hi-Touch LSIG electronic trip unit combines adjustable long-time overload, short-time selective short-circuit, instantaneous short-circuit and earth-fault protection with generator-specific functionality. Advanced measurement and Network Analyzer capabilities provide additional insight into electrical-system operation and power quality, while the modular Ekip architecture supports compatible communication and signalling options for integration into intelligent power-management and automation systems.
