Why Choose the ABB 1SDA059379R1 E3H1000 Air Circuit Breaker?
The ABB 1SDA059379R1 is a high-performance SACE Emax E3H1000 air circuit breaker (ACB) designed for protection and switching in demanding low-voltage electrical distribution systems. This four-pole fixed breaker combines a 1000 A rated current with ABB's advanced PR123/P electronic trip unit, providing comprehensive protection for critical industrial and commercial power distribution applications.
Configured with LSIG protection, the PR123/P electronic trip unit provides long-time, short-time, instantaneous and earth-fault protection functions. This comprehensive protection package makes the breaker particularly suitable for installations where selectivity, high fault-current interruption capability and earth-fault protection are required.
The E3H1000 offers an ultimate short-circuit breaking capacity of 100 kA at 415 V AC and 85 kA at 690 V AC. This configuration features four poles, fixed construction and rear horizontal terminals, making it suitable for high-performance switchboards and distribution systems requiring neutral switching alongside the three phase conductors.

Advanced Protection for High-Demand Power Distribution
Air circuit breakers such as the ABB SACE Emax E3H1000 protect low-voltage electrical installations against overloads, short circuits and earth faults while providing dependable switching and isolation. The high short-circuit performance of the E3H platform makes it particularly suitable for industrial distribution networks where substantial prospective fault currents may occur.
The PR123/P electronic trip unit provides comprehensive LSIG protection through long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault functions. Combined with the four-pole fixed Emax platform, this provides sophisticated protection for demanding distribution systems while enabling switching of the neutral conductor as part of the four-pole arrangement.
Typical Applications
- Main low-voltage electrical distribution boards.
- Industrial switchboards and switchgear assemblies.
- Transformer and generator distribution systems.
- Manufacturing and process plant electrical systems.
- Commercial and infrastructure power distribution.
- Four-pole systems requiring neutral switching and earth-fault protection.
- High-fault-level low-voltage distribution networks.
