1SDA056319R1 ABB E3S 3200 PR123/P-LSIG 3200A 4P Fixed Air Circuit Breaker

Why Choose the ABB E3S 3200 PR123/P-LSIG 3200A 4P Fixed Air Circuit Breaker?

The ABB 1SDA056319R1 is a high-performance SACE Emax E3S air circuit breaker designed for switching and protection in demanding high-current low-voltage power distribution systems. Rated at 3200 A, this four-pole fixed circuit breaker incorporates ABB's advanced PR123/P-LSIG electronic overcurrent release for comprehensive protection of industrial, commercial and infrastructure electrical networks.

Part of the proven ABB SACE Emax E3 series, the E3S 3200 combines substantial current-handling capability with strong short-circuit performance. The S performance level provides rated ultimate and service short-circuit breaking capacities of 75 kA across specified AC system voltages up to 690 V AC, making it suitable for demanding main distribution and high-fault-level applications.

The PR123/P-LSIG release provides long-time overload (L), short-time short-circuit (S), instantaneous short-circuit (I) and earth-fault (G) protection. This version features a four-pole fixed configuration with rear horizontal terminals and is fitted with four auxiliary contacts plus circuit-breaker open/closed position indication for integration into sophisticated low-voltage switchboards.

Advanced LSIG Protection for High-Current Distribution

Air circuit breakers such as the ABB E3S 3200 provide switching, isolation and automatic protection for high-current low-voltage distribution circuits. The electronic release monitors electrical conditions and commands the breaker to open when configured overload, short-circuit or earth-fault thresholds are reached, helping protect conductors, switchgear and connected equipment.

The PR123/P-LSIG release provides comprehensive long-time, short-time, instantaneous and earth-fault protection for sophisticated distribution networks. Combined with the E3S breaker's high short-circuit capability and fixed rear-horizontal-terminal configuration, the 1SDA056319R1 is particularly suited to critical switchboards requiring dependable high-current protection and advanced protection coordination.

Typical Applications

• Main incoming protection in low-voltage switchboards.
• Industrial power distribution systems.
• High-current feeder and distribution circuits.
• Manufacturing and process plant electrical systems.
• Commercial and infrastructure power distribution.
• Transformer and generator distribution switchboards.
• Critical installations requiring advanced LSIG electronic protection.
