1SDA056164R1 ABB E3N3200PR122/P-LSI 3200A 3-Pole Air Circuit Breaker Moving Part

Why Choose the ABB E3N3200PR122/P-LSI 3200A Air Circuit Breaker?

The ABB E3N3200PR122/P-LSI is a high-performance 3200 A three-pole air circuit breaker moving part designed for reliable switching and overcurrent protection in demanding low-voltage power distribution systems. As part of the established ABB SACE Emax New Emax series, this E3N configuration combines a robust high-current breaker frame with the advanced PR122/P-LSI electronic overcurrent release.

The PR122/P-LSI trip unit provides long-time overload, short-time short-circuit and instantaneous short-circuit protection. These LSI protection functions help safeguard cables, busbars, switchboards and connected electrical equipment against sustained overloads and short-circuit faults while supporting selective protection and coordination within complex electrical distribution networks.

With a rated uninterrupted current of 3200 A, a three-pole withdrawable moving-part configuration and a PR122/P-LSI R3200 release, ABB order code 1SDA056164R1 is designed for integration into compatible SACE Emax withdrawable switchgear. The moving part is fitted with four auxiliary contacts and circuit-breaker open/closed position indication for effective monitoring and control integration.

Reliable Protection for High-Current Power Distribution

Air circuit breakers such as the ABB E3N3200 provide switching and overcurrent protection for high-current low-voltage distribution circuits. The electronic trip release monitors circuit conditions and initiates breaker operation when configured protection thresholds are exceeded, helping protect cables, busbars, switchboards and connected electrical equipment against damaging overload and short-circuit currents.

The PR122/P-LSI release combines long-time, short-time and instantaneous protection functions in an electronic trip system. Together with the E3N frame's 65 kA short-circuit performance, 3200 A current rating and service-friendly withdrawable construction, this moving part is well suited to critical main distribution and high-current feeder applications.

Typical Applications

• Low-voltage main distribution switchboards.
• Industrial power distribution systems.
• Manufacturing and process facilities.
• Commercial and infrastructure electrical installations.
• Incoming mains and high-current feeder protection.
• Transformer secondary distribution systems.
• Withdrawable ABB SACE Emax switchgear assemblies.
