1SDA056684R1 ABB E3V 2500 PR122/P-LSI 2500 A 4-Pole Air Circuit Breaker

Why Choose the ABB 1SDA056684R1 E3V 2500 Air Circuit Breaker?

The ABB 1SDA056684R1 is a high-performance SACE Emax E3V air circuit breaker moving part designed for protection and switching in demanding low-voltage electrical distribution systems. Configured as an E3V 2500 PR122/P-LSI, this four-pole withdrawable unit combines a rated uninterrupted current of 2500 A with ABB's PR122/P electronic overcurrent release.

As part of the ABB SACE Emax series, the E3V 2500 is engineered for installations requiring high short-circuit performance, selective protection and dependable operation. The PR122/P-LSI release provides long-time, short-time and instantaneous protection functions, helping protect electrical installations against overloads and short circuits while supporting coordinated protection throughout the distribution system.

This configuration is a four-pole withdrawable moving part intended for use with a compatible SACE Emax fixed part. The E3V 2500 provides an ultimate short-circuit breaking capacity of 130 kA at 415 V AC and a short-time withstand current of 85 kA for 1 s, making it suitable for high-current, high-fault-level industrial and commercial power distribution systems.

Selective Four-Pole Protection for High-Current Distribution

Air circuit breakers such as the ABB SACE Emax E3V provide switching and protection for low-voltage electrical distribution systems where substantial prospective fault currents can occur. The E3V 2500 combines a 2500 A current rating with an ultimate short-circuit breaking capacity of 130 kA at 415 V AC, helping protect switchboards, busbars, cables and connected equipment against damaging overload and short-circuit conditions.

The PR122/P-LSI electronic trip unit combines long-time overload, short-time selective short-circuit and instantaneous short-circuit protection. Together with the four-pole and withdrawable construction, these functions make the 1SDA056684R1 well suited to high-current three-phase distribution systems where neutral switching, selective coordination and maintainable circuit protection are required.
