Why Choose the ABB E2L1600 PR122/P-LSIG Air Circuit Breaker?
The ABB E2L1600 PR122/P-LSIG, order code 1SDA056093R1, is a high-performance four-pole fixed air circuit breaker (ACB) designed for demanding low-voltage power distribution and protection applications. Part of the ABB SACE Emax E2 series, it combines a rated uninterrupted current of 1600 A with the advanced PR122/P-LSIG R1600 electronic overcurrent release.
The PR122/P-LSIG release provides long-time, short-time, instantaneous and ground-fault protection. These LSIG functions provide comprehensive protection against sustained overloads, short circuits and earth-fault conditions while supporting selective coordination in industrial, commercial and infrastructure electrical distribution systems.
This E2L1600 configuration uses fixed construction with rear horizontal terminals and is fitted with four change-over auxiliary contacts plus circuit-breaker open/closed position indication. With a rated voltage of 690 V AC and an ultimate short-circuit breaking capacity of 130 kA at 400 V AC, 50 Hz, it is engineered for installations with demanding prospective fault levels.
