1SDA056173R1 ABB E3N 3200 PR122/P-LSIG 3200A 4P Withdrawable Air Circuit Breaker

Why Choose the ABB E3N 3200 PR122/P-LSIG 3200A 4P Withdrawable Air Circuit Breaker?

The ABB 1SDA056173R1 is a high-performance SACE Emax E3N air circuit breaker moving part designed for protection and switching in high-current low-voltage electrical distribution systems. Rated at 3200 A, this four-pole withdrawable unit incorporates ABB's advanced PR122/P-LSIG electronic overcurrent release for comprehensive circuit protection in industrial and infrastructure installations.

Part of the established ABB SACE Emax E3 series, the E3N 3200 combines substantial current-handling capability with electronic protection and service-friendly withdrawable construction. Its N short-circuit performance level provides a rated ultimate and service short-circuit breaking capacity of 65 kA across specified AC system voltages up to 690 V AC, making it suitable for demanding main distribution applications.

The PR122/P-LSIG release provides long-time overload (L), short-time short-circuit (S), instantaneous short-circuit (I) and earth-fault (G) protection. The breaker is supplied as a withdrawable moving part with four auxiliary contacts and circuit-breaker open/closed position indication, supporting integration into sophisticated switchboards and power-management systems.

Reliable LSIG Protection for High-Current Distribution

Air circuit breakers such as the ABB E3N 3200 provide switching, isolation and automatic protection for high-current low-voltage distribution circuits. The electronic release monitors current conditions and commands the breaker to open when configured overload, short-circuit or earth-fault thresholds are reached, helping protect switchgear, conductors and connected equipment.

The PR122/P-LSIG release adds earth-fault protection to the long-time, short-time and instantaneous protection functions, providing a comprehensive LSIG protection package for complex distribution networks. Combined with the withdrawable Emax construction, the 1SDA056173R1 is well suited to switchboards requiring dependable protection, selective coordination and convenient servicing.

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.
