1SDA057125R1 ABB E6V5000 PR122/P-LSIG 5000 A 3-Pole Withdrawable Air Circuit Breaker

Why Choose the ABB 1SDA057125R1 E6V5000 Air Circuit Breaker?

The ABB 1SDA057125R1 is a high-performance SACE Emax E6V air circuit breaker moving part designed for protection and switching in demanding low-voltage power distribution systems. Identified as E6V5000 PR122/P-LSIG In=5000A 3p W, this three-pole withdrawable breaker combines a 5000 A rated current with the ABB PR122/P-LSIG electronic overcurrent release.

As part of the ABB SACE Emax E6V series, the breaker is engineered for high-current installations requiring dependable short-circuit performance, selective protection and maintainability. Its withdrawable construction allows the moving part to be isolated and removed from compatible switchgear, supporting inspection, servicing and replacement in critical industrial and infrastructure power distribution systems.

The integrated PR122/P-LSIG electronic trip unit provides long-time, short-time, instantaneous and ground-fault protection. With a rated operational voltage of up to 690 V AC and an ultimate short-circuit breaking capacity of up to 150 kA, the 1SDA057125R1 provides robust protection for high-capacity low-voltage electrical installations.

High-Performance Circuit Protection for 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. The breaker interrupts the circuit when configured protection thresholds are exceeded, helping safeguard switchgear, cables, transformers and connected electrical equipment against potentially damaging fault conditions.

The PR122/P-LSIG electronic release provides four principal protection functions. Long-time protection responds to sustained overload conditions, short-time protection supports selective coordination during short circuits, instantaneous protection provides rapid response to severe fault currents, and ground-fault protection detects potentially hazardous earth-fault conditions.

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 LSIG protection and selective coordination.
