Why Choose the ABB E3S3200PR121/P-LSI 3200A Air Circuit Breaker?
The ABB E3S3200PR121/P-LSI is a high-performance 3200 A four-pole air circuit breaker designed for reliable switching and overcurrent protection in demanding low-voltage power distribution systems. Part of the established ABB SACE Emax New Emax series, this E3S breaker combines robust high-current switching capability with the PR121/P-LSI electronic overcurrent release.
The PR121/P-LSI trip unit provides long-time overload, short-time short-circuit and instantaneous short-circuit protection. These LSI functions help safeguard cables, busbars, switchboards and connected electrical equipment against sustained overloads and short-circuit faults while supporting selective protection and coordination in industrial, commercial and infrastructure distribution networks.
With a rated current of 3200 A, a four-pole fixed configuration and rear horizontal terminals, ABB order code 1SDA056313R1 is designed for integration into high-current low-voltage switchboards. The breaker incorporates a PR121/P-LSI R3200 overcurrent release, four auxiliary contacts and circuit-breaker open/closed position indication for monitoring and control integration.

Reliable Protection for High-Current Power Distribution
Air circuit breakers such as the ABB E3S3200 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 PR121/P-LSI release combines long-time overload, short-time short-circuit and instantaneous short-circuit protection within a single electronic trip system. Together with the 3200 A four-pole E3S configuration, high short-circuit capability and fixed rear-horizontal-terminal construction, this breaker is well suited to critical main distribution and high-current feeder applications.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial power distribution systems.
- Three-phase four-wire distribution networks.
- Manufacturing and process facilities.
- Commercial and infrastructure electrical installations.
- Incoming mains and high-current feeder protection.
- Transformer secondary distribution systems.
- Data centre and critical-power distribution systems.
- Fixed ABB SACE Emax switchgear assemblies.
