1SDA056597R1 ABB E3V 1600 PR122/P-LSIG 1600 A Air Circuit Breaker

Why Choose the ABB 1SDA056597R1 E3V 1600 Air Circuit Breaker?

The ABB 1SDA056597R1 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 1600 PR122/P-LSIG, this three-pole fixed circuit breaker combines a rated current of 1600 A with ABB's PR122/P electronic overcurrent release.

As part of the ABB SACE Emax series, the E3V 1600 is engineered for installations requiring high short-circuit performance, selective protection and dependable operation. The PR122/P-LSIG release provides long-time, short-time, instantaneous and ground-fault protection functions, helping protect electrical installations against overloads, short circuits and earth faults while supporting coordinated protection throughout the distribution system.

This configuration is a three-pole fixed circuit breaker with horizontal rear terminals. The E3V 1600 frame provides a 125 kA short-circuit current rating at 480 V and 85 kA short-time withstand current, making it well suited to high-fault-level industrial switchboards and critical power distribution systems.
