Why Choose the ABB 1SDA059393R1 E3S1000 Air Circuit Breaker?
The ABB 1SDA059393R1 is a high-performance SACE Emax E3S 1000 A three-pole fixed air circuit breaker designed for comprehensive protection and switching in demanding low-voltage electrical distribution systems. Part of the ABB New Emax product family, it combines a 1000 A rated current with the PR121/P-LSIG electronic overcurrent release for industrial, commercial and infrastructure power applications.
The E3S1000 is equipped with an ABB PR121/P-LSIG R1000 electronic trip unit, providing long-time, short-time, instantaneous and earth-fault protection. The LSIG protection package helps safeguard cables, busbars, switchgear and connected equipment against overload, short-circuit and earth-fault conditions, with an overload adjustment range of 400–1000 A, short-time delayed short-circuit adjustment of 1000–10000 A and instantaneous adjustment of 1500–15000 A.
This model features a three-pole fixed configuration with rear horizontal terminals for permanent switchboard installation. The E3S platform provides rated service and ultimate short-circuit breaking capacities of 75 kA across 220–690 V AC, while four auxiliary change-over contacts and open/closed position indication support integration with switchboard control and signalling systems.

High-Performance Circuit Protection for Power Distribution
Air circuit breakers such as the ABB SACE Emax E3S protect low-voltage electrical distribution systems against potentially damaging overload, short-circuit and earth-fault conditions. The electronic trip unit monitors circuit current and initiates breaker operation when configured protection thresholds are exceeded, helping safeguard cables, busbars, switchgear and connected electrical equipment.
The PR121/P-LSIG release combines long-time overload, short-time delayed short-circuit, instantaneous short-circuit and earth-fault protection with the high fault-interruption capability of the E3S platform. Together with its 75 kA short-time withstand current for 1 s and fixed three-pole construction, the 1SDA059393R1 is well suited to critical distribution systems requiring comprehensive electronic protection and robust high-current switchgear.
Typical Applications
- Industrial low-voltage switchboards.
- Main incoming and distribution circuits.
- Three-phase electrical distribution systems.
- Manufacturing and process facilities.
- Commercial building power distribution.
- Electrical distribution panels and assemblies.
- Infrastructure and utility installations.
- Systems with high prospective short-circuit currents requiring fixed air circuit breakers.
