1SDA056331R1 ABB E3S3200 PR122/P-LI 3200A 4P Withdrawable Air Circuit Breaker

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

The ABB E3S3200 PR122/P-LI, order code 1SDA056331R1, 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 is rated at 3200 A, has a four-pole configuration and incorporates ABB's electronic PR122/P-LI overcurrent release.

Designed for a withdrawable installation, the E3S3200 moving part enables convenient isolation and servicing within compatible SACE Emax switchgear. Its S performance level provides a rated ultimate short-circuit breaking capacity of 75 kA at 400 V AC, supporting high-capacity industrial and infrastructure distribution systems.

The PR122/P-LI electronic release provides long-time overload and instantaneous short-circuit protection, with an overload adjustment range of 1280–3200 A. Its four-pole construction, 690 V AC rated voltage and withdrawable format make the 1SDA056331R1 suitable for main incomers, feeders and other critical high-current distribution circuits.

Reliable High-Current Protection for Low-Voltage Distribution

Air circuit breakers such as the ABB SACE Emax E3S3200 protect high-current electrical distribution circuits against damaging overload and short-circuit conditions. The PR122/P-LI electronic release combines adjustable long-time overload protection with instantaneous short-circuit protection, helping safeguard cables, busbars and connected distribution equipment.

The withdrawable moving-part design is particularly suited to industrial switchboards where serviceability and operational flexibility are important. The breaker can be disconnected from its compatible fixed part for isolation and 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 circuit protection and serviceability.
