1SDA060905R1 ABB E3V-A 3200 PR122/P-LSIG 3200A 3P Air Circuit Breaker

Why Choose the ABB E3V-A 3200 PR122/P-LSIG 3200A 3P Air Circuit Breaker?

The ABB E3V-A 3200 PR122/P-LSIG, order code 1SDA060905R1, is a high-performance SACE Emax air circuit breaker moving part designed for protection and switching in high-current low-voltage distribution systems. Rated at 3200 A, this three-pole E3V-A breaker is equipped with ABB's advanced PR122/P-LSIG electronic overcurrent release for comprehensive circuit protection.

As part of the ABB SACE Emax family, the E3V-A combines high current capacity with electronic protection suitable for demanding industrial and commercial power-distribution installations. The PR122/P-LSIG release provides long-time, short-time, instantaneous and earth-fault protection functions, allowing the breaker to protect electrical networks against overloads, short circuits and earth faults.

This configuration is a three-pole withdrawable moving part with a 3200 A rating plug. ABB identifies the unit as a UL E3V-A circuit-breaker moving part fitted with four auxiliary contacts and circuit-breaker open/closed position indication, making it suitable for switchboards where maintainability, status monitoring and dependable high-current protection are essential.

Reliable Circuit Protection for High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax E3V-A protect low-voltage electrical distribution systems by interrupting excessive current before it can cause serious damage to conductors, switchgear and connected equipment. The PR122/P-LSIG electronic release continuously supports protection against overload, short-time and instantaneous short-circuit conditions, together with earth faults.

The withdrawable architecture is particularly valuable in critical switchboards because the breaker moving part can be isolated from its fixed cradle for inspection, servicing or replacement. Combined with its 3200 A current rating and integrated auxiliary signalling, the E3V-A 3200 is suited to high-capacity distribution systems requiring dependable protection and serviceability.

Typical Applications

• Industrial low-voltage main distribution switchboards.
• High-current incoming and feeder protection.
• Manufacturing and process-industry power distribution.
• Commercial and infrastructure electrical distribution systems.
• Power distribution centres and switchgear assemblies.
• Critical electrical installations requiring withdrawable circuit breakers.
