Why Choose the ABB 1SDA057389R1 E3N-A 2000 Air Circuit Breaker?
The ABB 1SDA057389R1 is a SACE Emax E3N-A air circuit breaker moving part designed for protection and switching in demanding low-voltage power distribution systems. Identified as E3N-A 2000 PR122/P-LSIG In=2000A 3p W MP, this three-pole withdrawable breaker combines a 2000 A rated current with the ABB PR122/P-LSIG electronic overcurrent release.
As part of the ABB SACE Emax E3 platform, this UL-oriented E3N-A configuration is designed for industrial, commercial and infrastructure installations requiring dependable high-current circuit protection. Its withdrawable moving-part construction allows the breaker to be isolated and removed from compatible switchgear, supporting inspection, servicing and replacement in critical power distribution systems.
The integrated PR122/P-LSIG electronic trip unit provides long-time, short-time, instantaneous and ground-fault protection. The breaker is also fitted with four auxiliary contacts and open/closed position indication, supporting status signalling and integration with switchboard monitoring and control systems.

Comprehensive LSIG Protection for High-Current Power Distribution
Air circuit breakers such as the ABB SACE Emax E3N-A are used to switch and protect substantial low-voltage electrical loads. When abnormal current conditions occur, the electronic trip unit evaluates the fault against its configured protection settings and initiates circuit interruption when required, helping safeguard switchgear, conductors, transformers, generators and connected electrical equipment.
The PR122/P-LSIG release provides four principal protection functions. Long-time protection responds to sustained overload conditions, short-time protection supports controlled short-circuit response and selective coordination, instantaneous protection provides rapid interruption during severe short circuits, and ground-fault protection detects potentially damaging current flowing to earth.
Typical Applications
- Main low-voltage distribution switchboards.
- Industrial power distribution systems.
- Manufacturing and process facilities.
- Commercial building electrical distribution.
- Infrastructure and utility power systems.
- Transformer secondary distribution.
- Generator distribution and protection systems.
- Switchgear requiring a 2000 A three-pole withdrawable air circuit breaker with LSIG electronic protection.
