1SDA057111R1 ABB E6V5000 PR123/P-LSIG 5000 A 3-Pole Fixed Air Circuit Breaker

Why Choose the ABB 1SDA057111R1 E6V5000 Air Circuit Breaker?

The ABB 1SDA057111R1 is a high-performance SACE Emax E6V air circuit breaker designed for protection and switching in demanding low-voltage power distribution systems. Identified as E6V5000 PR123/P-LSIG In=5000A 3p F, this three-pole fixed circuit breaker combines a 5000 A rated current with the advanced ABB PR123/P-LSIG electronic overcurrent release.

As part of the ABB SACE Emax E6V series, the breaker is engineered for high-current installations where dependable fault protection, selectivity and advanced monitoring are required. Its fixed construction with rear horizontal terminals enables permanent integration into compatible low-voltage switchboards, while the E6V performance class is intended for systems with demanding prospective short-circuit currents.

The integrated PR123/P-LSIG electronic trip unit provides long-time, short-time, instantaneous and ground-fault protection. The PR123/P platform also supports advanced measurement and monitoring functionality, making the 1SDA057111R1 particularly suitable for sophisticated industrial and infrastructure power distribution systems where protection and electrical system visibility are important.

Advanced Circuit Protection for High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax E6V protect high-current low-voltage distribution systems against overloads, short circuits and earth faults. When configured protection thresholds are exceeded, the circuit breaker can interrupt the affected circuit, helping safeguard switchgear, cables, transformers and connected electrical equipment.

The PR123/P-LSIG electronic release provides comprehensive protection together with advanced monitoring capabilities. Long-time protection responds to sustained overload conditions, short-time protection supports selective coordination, instantaneous protection provides rapid response to severe short circuits, and ground-fault protection detects potentially hazardous earth-fault currents.

Typical Applications

• Main low-voltage distribution switchboards.
• High-current industrial power distribution systems.
• Manufacturing and process plants.
• Commercial and infrastructure electrical installations.
• Transformer secondary distribution.
• Generator and installation protection systems.
• High-fault-level switchgear assemblies.
• Power distribution systems requiring advanced LSIG protection, measurement and monitoring.
