1SDA056325R1 ABB E3S3200 PR122/P-LSIG 3200A 3-Pole Withdrawable Air Circuit Breaker

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

The ABB E3S3200 PR122/P-LSIG, order code 1SDA056325R1, 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 advanced PR122/P-LSIG electronic overcurrent release.

The PR122/P-LSIG trip unit provides long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection. This comprehensive LSIG configuration supports selective coordination while protecting electrical distribution equipment against sustained overloads, short circuits and earth faults in demanding industrial, commercial and infrastructure installations.

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 and comprehensive protection are important. The E3S performance level provides a rated ultimate short-circuit breaking capacity of 75 kA at 400 V AC, while the breaker is supplied with four auxiliary change-over contacts and open/closed position indication.

Advanced 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 conditions and initiates circuit-breaker operation when configured protection thresholds are exceeded, helping protect cables, switchgear and connected equipment against damaging overloads, short circuits and earth faults.

The PR122/P-LSIG release provides four complementary protection functions for effective coordination within electrical distribution systems. Long-time protection responds to sustained overloads, short-time protection supports selective fault clearing, instantaneous protection rapidly interrupts severe short circuits, and ground-fault protection provides an additional protective function against earth-fault conditions. The withdrawable construction also enables the breaker moving part to be removed from its associated fixed part for inspection, servicing 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.
