1SDA057365R1 ABB E2N-A 1600 PR123/P-LSIG 1600 A 3-Pole Withdrawable Air Circuit Breaker

Why Choose the ABB 1SDA057365R1 E2N-A 1600 Air Circuit Breaker?

The ABB 1SDA057365R1 is a SACE Emax E2N-A air circuit breaker moving part designed for protection and switching in demanding low-voltage power distribution systems. Identified as E2N-A 1600 PR123/P-LSIG In=1600A 3p W MP, this three-pole withdrawable breaker combines a 1600 A rated current with the advanced ABB PR123/P-LSIG electronic overcurrent release.

As part of the ABB SACE Emax E2 platform, this UL-oriented E2N-A configuration is suitable 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 while maintaining a flexible switchboard architecture.

The integrated PR123/P-LSIG electronic trip unit provides long-time, short-time, instantaneous and ground-fault protection together with advanced measurement and monitoring capabilities. The breaker is also equipped with four auxiliary contacts and open/closed position indication, supporting status signalling and integration with switchboard monitoring and control systems.

Advanced LSIG Protection for Low-Voltage Power Distribution

Air circuit breakers such as the ABB SACE Emax E2N-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 PR123/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. Its advanced measurement and monitoring capabilities provide additional visibility into electrical system operating conditions.

Typical Applications

• Main low-voltage distribution switchboards.
• Industrial power distribution systems.
• Manufacturing and process facilities.
• Commercial building electrical distribution.
• Infrastructure power systems.
• Transformer secondary distribution.
• Generator distribution and protection systems.
• Switchgear requiring a 1600 A three-pole withdrawable air circuit breaker with advanced LSIG electronic protection.
