Why Choose the ABB E3V 2500 PR122/P-LSI Air Circuit Breaker?
The ABB E3V 2500 PR122/P-LSI, order code 1SDA056676R1, is a high-performance withdrawable air circuit breaker (ACB) moving part designed for demanding low-voltage power distribution systems. Part of the established ABB SACE Emax E3V series, this three-pole breaker combines a 2500 A rated current with the PR122/P-LSI R2500 electronic overcurrent release.
The PR122/P-LSI release provides long-time, short-time and instantaneous overcurrent protection, helping safeguard electrical installations against sustained overloads and short-circuit faults. The E3V performance class provides substantial breaking capability, making this breaker suitable for industrial, commercial and infrastructure distribution systems with demanding prospective fault levels.
This model is supplied as a 3-pole withdrawable moving part (W MP) for use with a compatible ABB SACE Emax fixed part. It is fitted with four change-over auxiliary contacts and open/closed circuit-breaker position indication, supporting integration with switchboard signalling, monitoring and control systems.

Reliable LSI Protection for High-Current Distribution
The ABB E3V 2500 combines substantial current-carrying capability with the PR122/P-LSI electronic overcurrent release. Long-time protection helps safeguard circuits against sustained overload conditions, short-time protection supports coordinated response to short circuits, and instantaneous protection provides rapid interruption of severe fault currents.
Its withdrawable SACE Emax construction is particularly suited to switchboards where serviceability and operational flexibility are important. The breaker moving part interfaces with a compatible fixed part and can be withdrawn for inspection, maintenance or replacement, while the E3V breaking performance supports demanding high-fault-level distribution applications.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial three-phase power distribution systems.
- Manufacturing and process plants.
- Commercial and infrastructure electrical installations.
- Transformer and generator distribution systems.
- Power control centres and withdrawable switchgear assemblies.
