Why Choose the ABB 1SDA059223R1 E1N 1000 Air Circuit Breaker?
The ABB 1SDA059223R1 is a SACE Emax E1N 1000 air circuit breaker designed for protection and switching in industrial low-voltage power-distribution systems. This four-pole fixed version is rated at 1000 A and is equipped with ABB's PR121/P-LSIG electronic overcurrent release.
The PR121/P-LSIG release provides long-time (L), short-time (S), instantaneous (I) and earth-fault (G) protection functions. This LSIG configuration provides comprehensive protection against sustained overloads, short-circuit conditions and earth faults, making the breaker suitable for important main-distribution and feeder applications.
The E1N performance level combines substantial short-circuit capability with a compact E1-frame architecture. The 1SDA059223R1 uses a fixed four-pole configuration, making it suitable for permanent installation in compatible ABB SACE Emax switchboards where comprehensive electronic protection and four-pole circuit switching are required.
