Why Choose the ABB 1SDA059189R1 E1B 1000 Air Circuit Breaker?
The ABB 1SDA059189R1 is a SACE Emax E1B 1000 air circuit breaker designed for dependable protection and switching in industrial low-voltage power-distribution systems. This three-pole fixed version is rated at 1000 A and is equipped with ABB's PR122/P-LSIG R1000 electronic overcurrent release.
The PR122/P-LSIG provides long-time (L), short-time (S), instantaneous (I) and earth-fault (G) protection functions. This combination provides comprehensive electronic protection against sustained overloads, short circuits and earth faults, making the breaker suitable for critical main-distribution and feeder applications.
The 1SDA059189R1 is a fixed circuit breaker with rear horizontal terminals, providing a robust arrangement for permanent switchboard installation. It is also fitted with four auxiliary contacts for circuit-breaker open/closed position signalling, supporting integration with switchboard monitoring and control systems.
