Why Choose the ABB E2N-A 1600 PR122/P-LSIG Air Circuit Breaker?
The ABB E2N-A 1600 PR122/P-LSIG, order code 1SDA057357R1, is a SACE Emax moving part for an air circuit breaker designed for high-current low-voltage AC power distribution systems. This UL configuration has a rated current of 1600 A, a three-pole arrangement and an advanced PR122/P-LSIG electronic overcurrent release.
As part of the ABB SACE Emax E2N-A series, the 1SDA057357R1 combines robust power switching with comprehensive electronic protection. Its PR122/P-LSIG release provides long-time, short-time, instantaneous and ground-fault protection functions, enabling coordinated protection of feeders, busbars and connected electrical equipment in demanding power distribution installations.
This specific version is the withdrawable moving part (W MP) of the circuit breaker rather than the fixed version. It is equipped with the PR122/P-LSIG R1600 release, four auxiliary contacts and open/closed position indication, making it suitable for switchboards where maintainability, breaker replacement and operational flexibility are important.

Reliable Circuit Protection for Power Distribution
Air circuit breakers in the ABB SACE Emax range provide switching and overcurrent protection for high-current low-voltage distribution systems. The electronic trip release monitors electrical conditions and initiates circuit interruption when configured protection thresholds are exceeded, helping protect distribution equipment against overloads, short circuits and earth faults.
The withdrawable moving-part construction of the 1SDA057357R1 is particularly useful in switchboards where serviceability and operational continuity are priorities. Combined with PR122/P-LSIG protection and auxiliary status contacts, it provides a versatile solution for sophisticated industrial and commercial power distribution assemblies.
Typical Applications
- Industrial low-voltage power distribution systems.
- Withdrawable main switchboards and distribution boards.
- Manufacturing plant electrical distribution.
- Commercial and infrastructure power systems.
- Protection of high-current feeders and busbar systems.
- Power distribution installations requiring LSIG protection and withdrawable breaker construction.
