Why Choose the ABB 1SDA125824R1 Emax 3 E6.3X 5000 Ekip Aware LSI 4p WMP?
The ABB 1SDA125824R1 is a high-performance low-voltage air circuit breaker (ACB) designed for reliable protection and switching in demanding electrical distribution systems. As part of the advanced ABB SACE Emax 3 E6.3X series, this four-pole withdrawable circuit breaker combines a 5000 A rated current with an Ekip Aware LSI electronic trip unit for intelligent overcurrent protection.
The Emax 3 platform combines advanced protection, intelligent power management, sensing and connectivity capabilities for modern low-voltage power infrastructure. The Ekip Aware release provides intelligent protection functionality, while the withdrawable WMP configuration supports convenient inspection, maintenance and servicing.
With a rated current of 5000 A, a 150 kA short-circuit breaking capacity at 440 V AC and a 120 kA short-time withstand current for 1 s, the ABB 1SDA125824R1 is suited to high-current main distribution systems, industrial switchboards and critical electrical infrastructure requiring very high fault-interruption performance.
