1SDA056636R1 ABB E3V 2000 PR122/P-LSI 2000 A 4-Pole Air Circuit Breaker

Why Choose the ABB 1SDA056636R1 E3V 2000 Air Circuit Breaker?

The ABB 1SDA056636R1 is a high-performance SACE Emax E3V air circuit breaker (ACB) designed for protection and switching in demanding low-voltage electrical distribution systems. Configured as an E3V 2000 PR122/P-LSI, this four-pole fixed circuit breaker combines a rated current of 2000 A with ABB's PR122/P electronic overcurrent release.

As part of the ABB SACE Emax series, the E3V 2000 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 selective coordination throughout the distribution system.

This configuration is a four-pole fixed air circuit breaker, allowing switching and isolation of all four conductors in suitable three-phase systems with a neutral. The E3V performance level is designed for high-fault-level applications, making the 1SDA056636R1 suitable for main incomers, distribution feeders and other critical high-current switchboard applications.
