1SDA056332R1 ABB E3S3200 PR122/P-LSI 3200A 4P Withdrawable Air Circuit Breaker

Why Choose the ABB E3S3200 PR122/P-LSI 3200A 4P Withdrawable Air Circuit Breaker?

The ABB E3S3200 PR122/P-LSI, order code 1SDA056332R1, is a high-performance SACE Emax air circuit breaker moving part designed for protection and switching in demanding low-voltage electrical distribution systems. This E3S breaker has a rated current of 3200 A, a four-pole configuration and ABB's electronic PR122/P-LSI overcurrent release.

Designed as the moving portion of a withdrawable circuit-breaker installation, the E3S3200 supports convenient isolation and servicing within compatible SACE Emax switchgear. The E3S performance level provides high short-circuit capability for industrial and infrastructure distribution systems where dependable protection of high-current circuits is essential.

The PR122/P-LSI electronic release provides long-time overload, short-time short-circuit and instantaneous short-circuit protection. Combined with the breaker's 3200 A rating, four-pole architecture and withdrawable construction, this configuration is well suited to main incomers, high-current feeders and critical power distribution applications.

Reliable High-Current Protection for Low-Voltage Distribution

Air circuit breakers such as the ABB SACE Emax E3S3200 protect high-current electrical distribution systems against overload and short-circuit conditions. The PR122/P-LSI electronic release combines long-time, short-time and instantaneous protection functions, allowing coordinated protection against sustained overloads and different levels of short-circuit fault.

The withdrawable moving-part design is particularly valuable in industrial switchboards where serviceability and operational flexibility are important. The breaker can be isolated from its compatible fixed part for inspection or maintenance, while its 3200 A rating and four-pole architecture support demanding three-phase power distribution systems.

Typical Applications

• Main incoming protection for industrial low-voltage switchboards.
• High-current feeder and distribution circuit protection.
• Manufacturing plants and process facilities.
• Commercial and infrastructure power distribution systems.
• Large motor control centres and electrical distribution assemblies.
• Withdrawable switchgear requiring high-current protection and serviceability.
