Why Choose the ABB E4V-A 3200 PR122/P-LSI Air Circuit Breaker?
The ABB E4V-A 3200 PR122/P-LSI, order code 1SDA057961R1, is a high-performance three-pole air circuit breaker (ACB) from the ABB SACE Emax range, engineered for switching and protection in high-current low-voltage electrical distribution systems. With a rated current of 3200 A, the E4V-A combines heavy-duty circuit interruption with the advanced PR122/P-LSI electronic trip unit.
The PR122/P-LSI release provides electronic long-time (L), short-time (S) and instantaneous (I) protection functions. This combination protects conductors and distribution equipment against overload and short-circuit conditions while providing the flexibility required for coordinated protection in complex electrical networks.
This configuration is a three-pole withdrawable circuit breaker moving part rated at 3200 A. Its withdrawable construction is designed for compatible SACE Emax switchgear, allowing the breaker to be disconnected and removed from its fixed part for inspection, maintenance or replacement without permanently disturbing the main power connections.

Reliable Protection for High-Current Distribution Systems
Air circuit breakers such as the ABB E4V-A are used to protect main incoming supplies, busbars and high-current distribution feeders against potentially damaging electrical faults. The electronic trip unit monitors current conditions and initiates breaker operation when configured overload or short-circuit protection thresholds are exceeded.
The PR122/P-LSI release provides adjustable electronic protection for coordinated low-voltage distribution networks. Combined with the withdrawable E4 construction, it provides a practical solution for switchgear where high interruption performance, protection selectivity and serviceability are important requirements.
Typical Applications
- Main incoming protection in low-voltage switchboards.
- Industrial power distribution systems.
- High-current feeder and busbar protection.
- Manufacturing and process plant electrical systems.
- Commercial and infrastructure power distribution.
- Withdrawable low-voltage switchgear assemblies.
