Why Choose the ABB SACE Emax 3 E2.3S 1250 1SDA128943R1 Air Circuit Breaker?
The ABB 1SDA128943R1 is a high-performance SACE Emax 3 air circuit breaker moving part designed for reliable protection and control of low-voltage electrical distribution systems. Configured as an E2.3S 1250 three-pole withdrawable circuit breaker, it combines a 1250 A rated current with an Ekip Aware LSIG electronic trip unit for comprehensive protection and monitoring.
This ABB SACE Emax 3 circuit breaker incorporates an Ekip Aware LSIG trip unit providing long-time, short-time, instantaneous and earth-fault protection functions. The withdrawable construction allows the moving part to be withdrawn from the corresponding fixed installation, supporting practical maintenance and system servicing in industrial switchboards.
With a rated current of 1250 A and a rated ultimate short-circuit breaking capacity of 85 kA at 415 V, the E2.3S 1250 is suited to demanding low-voltage power distribution applications. This product is supplied as the moving part only (WMP); the compatible fixed part is ordered separately.

Reliable Protection for Low-Voltage Power Distribution
Air circuit breakers such as the ABB SACE Emax 3 E2.3S 1250 provide high-current switching and protection for electrical distribution systems. The circuit breaker can interrupt fault currents when required while its electronic trip unit manages the configured protection functions.
The Ekip Aware LSIG trip unit combines long-time, short-time, instantaneous and earth-fault protection functions, providing comprehensive protection for electrical distribution equipment. The withdrawable construction also supports maintenance procedures by allowing the moving part to be separated from the fixed installation.
Typical Applications
- Industrial low-voltage power distribution switchboards.
- Commercial and industrial electrical distribution systems.
- High-current feeder and incoming circuit protection.
- Power distribution panels and switchgear assemblies.
- Industrial plants and infrastructure electrical systems.
- Applications requiring withdrawable air circuit breaker technology.
