Why Choose the ABB 1SDA059236R1 E1N 1000 Air Circuit Breaker?
The ABB 1SDA059236R1 is a SACE Emax E1N 1000 air circuit breaker moving part engineered for protection and switching in industrial low-voltage power-distribution systems. This four-pole withdrawable configuration is rated at 1000 A and incorporates ABB's PR122/P-LSIG electronic overcurrent release.
The PR122/P-LSIG provides long-time (L), short-time (S), instantaneous (I) and earth-fault (G) protection functions. This comprehensive LSIG protection package enables the breaker to respond to sustained overloads, short-circuit conditions and earth faults, making it suitable for important main incomer, feeder and distribution applications.
As a withdrawable moving part, the 1SDA059236R1 is designed for use with the appropriate ABB SACE Emax E1 fixed part. The draw-out architecture supports switchgear installations where maintainability, inspection and convenient replacement of the breaker moving part are important operational requirements.
