Why Choose the ABB SACE Emax 3 E6.3X 4000 1SDA128968R1 Air Circuit Breaker?
The ABB 1SDA128968R1 is a high-performance SACE Emax 3 air circuit breaker moving part designed for reliable protection and control of high-current low-voltage electrical distribution systems. Configured as an E6.3X 4000 three-pole withdrawable circuit breaker, it combines a 4000 A rated current with an Ekip Aware LSIG electronic trip unit for comprehensive electrical protection.
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. Its withdrawable construction allows the moving part to be withdrawn from the corresponding fixed installation, supporting practical inspection, maintenance and servicing of industrial switchgear.
With a rated current of 4000 A and a rated ultimate short-circuit breaking capacity of 150 kA at 415 V, the E6.3X 4000 is designed for demanding low-voltage power distribution applications where a very high short-circuit breaking capacity is required. 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 E6.3X 4000 provide high-current switching and protection for low-voltage electrical distribution systems. The circuit breaker is designed to 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 very high short-circuit breaking capacity and withdrawable air circuit breaker technology.
