1SDA056324R1 ABB E3S3200 PR122/P-LSI 3200A 3-Pole Withdrawable Air Circuit Breaker

Why Choose the ABB E3S3200 PR122/P-LSI 3200A 3-Pole Withdrawable Air Circuit Breaker?

The ABB E3S3200 PR122/P-LSI, order code 1SDA056324R1, is a high-performance SACE Emax air circuit breaker (ACB) moving part designed for switching and protection in high-current low-voltage electrical distribution systems. As part of the ABB SACE Emax E3 series, this three-pole withdrawable breaker combines a 3200 A rated uninterrupted current with the 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. This LSI configuration supports selective coordination and dependable protection against sustained overloads and short-circuit faults, making the breaker suitable for demanding industrial, commercial and infrastructure power distribution applications.

With a 3200 A rated current, three-pole configuration and withdrawable moving-part construction, the E3S3200 is suited to main switchboards and high-current distribution systems where maintainability is important. The E3S performance level provides rated ultimate and service short-circuit breaking capacities of 75 kA at 415 V AC, together with short-time withstand ratings of 75 kA for 1 s and 65 kA for 3 s.

Reliable Circuit Protection for High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax E3S3200 provide switching, isolation and overcurrent protection for high-current low-voltage distribution circuits. The electronic trip unit monitors electrical current and initiates circuit-breaker operation when configured protection thresholds are exceeded, helping protect cables, switchgear and connected electrical equipment against damaging overloads and short circuits.

The PR122/P-LSI release provides three levels of overcurrent protection for effective coordination within electrical distribution systems. Long-time protection responds to sustained overloads, short-time protection enables a controlled response to short-circuit conditions for improved selectivity, and instantaneous protection provides rapid interruption of severe short-circuit currents. The withdrawable construction also enables the breaker moving part to be removed from its associated fixed part for maintenance or replacement.

Typical Applications

• Main low-voltage electrical distribution switchboards.
• Industrial power distribution systems.
• Commercial and infrastructure electrical installations.
• Manufacturing and process facilities.
• High-current incomer and feeder protection.
• Transformer and generator distribution systems.
