1SDA071576R1 ABB E2.2H 1000 Ekip Touch LSIG 4-Pole Air Circuit Breaker

Why Choose the ABB 1SDA071576R1 E2.2H 1000 Ekip Touch LSIG Air Circuit Breaker?

The ABB 1SDA071576R1 is a high-performance SACE Emax 2 E2.2H air circuit breaker designed for reliable protection, switching and isolation in demanding low-voltage power distribution systems. Configured as an E2.2H 1000 Ekip Touch LSIG 4p F HR, it combines a 1000 A rated current, four-pole construction and ABB's advanced Ekip Touch LSIG electronic protection release.

As part of the ABB SACE Emax 2 series, this breaker provides comprehensive electronic protection against overload, short-circuit and earth-fault conditions. The Ekip Touch LSIG release provides Long-time (L), Short-time (S), Instantaneous (I) and Ground-fault (G) protection functions, together with an intuitive touchscreen interface for protection configuration and monitoring.

The 1SDA071576R1 is a fixed four-pole circuit breaker with rear flat horizontal terminals. With a rated operational voltage of 690 V AC and an ultimate short-circuit breaking capacity of 100 kA at 400/415 V AC and 85 kA at 690 V AC, it is suited to demanding industrial switchboards, commercial distribution systems and critical low-voltage power installations.

Reliable Protection for Low-Voltage Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 provide switching, isolation and protection for high-current low-voltage distribution circuits. The electronic trip unit monitors electrical conditions and initiates circuit interruption when configured protection thresholds are exceeded, helping protect cables, switchgear and connected equipment against overload, short-circuit and earth-fault conditions.

The Ekip Touch LSIG release combines adjustable long-time overload, selective short-time, instantaneous short-circuit and ground-fault protection with a touchscreen interface for configuration and monitoring. Together with the high-breaking-capacity E2.2H frame, four-pole construction, fixed execution and rear horizontal terminals, the 1SDA071576R1 provides a robust protection solution for demanding industrial and commercial power distribution systems.

Typical Applications

• Industrial low-voltage switchboards and distribution panels.
• Main incoming and outgoing power distribution circuits.
• Transformer secondary distribution and protection.
• Industrial plants and manufacturing facilities.
• Commercial buildings and infrastructure power distribution.
• Generator and critical power distribution systems.
