Why Choose the ABB E3V-A 2500 PR122/P-LSIG Air Circuit Breaker?
The ABB E3V-A 2500 PR122/P-LSIG, order code 1SDA057805R1, is a high-performance SACE Emax air circuit breaker moving part designed for protection and switching in demanding low-voltage power distribution systems. Rated at 2500 A, this three-pole breaker combines the E3V-A frame with ABB's advanced PR122/P-LSIG electronic overcurrent release for comprehensive circuit protection.
As part of the ABB SACE Emax range, the E3V-A is engineered for industrial switchboards, power distribution assemblies and infrastructure where high current capacity, serviceability and robust fault protection are required. This version is the withdrawable moving part (W / MP), enabling use with the appropriate fixed cradle and supporting convenient isolation and maintenance within switchgear assemblies.
The E3V-A 2500 configuration has a rated current of 2500 A and a three-pole arrangement. Its PR122/P-LSIG electronic trip unit provides long-time, short-time, instantaneous and ground-fault protection, while this UL configuration is identified with an R2500 release and an instantaneous setting reference of 37500 A.

Reliable Protection for High-Current Power Distribution
Air circuit breakers such as the ABB SACE Emax E3V-A protect low-voltage electrical systems against damaging overload, short-circuit and earth-fault conditions. The PR122/P-LSIG electronic release provides long-time overload, short-time selective, instantaneous short-circuit and ground-fault protection, allowing multiple protection functions to be coordinated within a single breaker.
The withdrawable moving-part construction is particularly suited to switchboard applications where serviceability and operational flexibility are important. When installed with the appropriate SACE Emax fixed part, the breaker can be isolated and withdrawn for inspection or maintenance, making it well suited to critical industrial and infrastructure power distribution systems.
Typical Applications
- Industrial low-voltage switchboards.
- Main incoming and distribution circuit protection.
- Power distribution centres and switchgear assemblies.
- Manufacturing and process plants.
- Commercial and infrastructure power distribution.
- High-current electrical distribution systems requiring withdrawable circuit breakers.
