Why Choose the ABB E3V 2500 PR122/P-LI Air Circuit Breaker?
The ABB E3V 2500 PR122/P-LI, order code 1SDA056675R1, 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-LI R2500 electronic overcurrent release.
The PR122/P-LI release provides long-time and instantaneous overcurrent protection, helping safeguard electrical installations against sustained overloads and severe short circuits. With the E3V short-circuit performance level, the breaker is engineered for high-fault-current industrial, commercial and infrastructure distribution applications.
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 auxiliary contacts and circuit-breaker open/closed position indication, supporting integration into switchboard signalling, monitoring and control systems.

Reliable Electronic Protection for High-Current Distribution
The ABB E3V 2500 combines substantial current-carrying capability with the PR122/P-LI electronic overcurrent release. Long-time protection helps protect circuits against sustained overload conditions, while instantaneous protection provides rapid interruption of severe short circuits, helping safeguard busbars, cables, transformers and connected electrical equipment.
Its withdrawable construction is particularly useful in switchboards where serviceability and operational flexibility are important. The breaker moving part interfaces with a compatible fixed part and can be withdrawn for inspection, servicing or replacement, while its high E3V breaking capacity supports installations with demanding prospective fault levels.
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.
