Why Choose the ABB E4V-A 3200 PR123/P-LSIG Air Circuit Breaker?
The ABB E4V-A 3200 PR123/P-LSIG, order code 1SDA057973R1, 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 3200 A, this three-pole breaker combines the E4V-A frame with ABB's advanced PR123/P-LSIG electronic overcurrent release for comprehensive circuit protection.
As part of the ABB SACE Emax range, the E4V-A is engineered for industrial switchboards, power distribution assemblies and infrastructure installations requiring high current capacity and dependable protection. This version is a withdrawable (W) moving part (MP), providing a serviceable breaker arrangement for use with the corresponding SACE Emax fixed part.
The E4V-A 3200 configuration has a rated current of 3200 A, a three-pole arrangement and an R3200 overcurrent release. Its PR123/P-LSIG electronic trip unit provides long-time, short-time, instantaneous and ground-fault protection, with an instantaneous setting reference of 48000 A for demanding high-current distribution applications.

Reliable Protection for High-Current Power Distribution
Air circuit breakers such as the ABB SACE Emax E4V-A protect low-voltage electrical systems against damaging overload, short-circuit and ground-fault conditions. The PR123/P-LSIG electronic release combines 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 useful in switchgear where serviceability and operational flexibility are important. When installed with the corresponding SACE Emax fixed part, the 3200 A breaker can be isolated and withdrawn for inspection or maintenance while providing comprehensive LSIG protection for demanding high-current distribution circuits.
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 systems requiring withdrawable circuit breakers.
