Why Choose the ABB 1SDA059245R1 E1N 1000 Air Circuit Breaker?
The ABB 1SDA059245R1 is a SACE Emax E1N 1000 air circuit breaker designed for reliable protection and switching in demanding industrial low-voltage power-distribution systems. This three-pole fixed version is rated at 1000 A and is equipped with ABB's advanced PR123/P-LSIG R1000 electronic overcurrent release.
The PR123/P-LSIG provides long-time (L), short-time (S), instantaneous (I) and earth-fault (G) protection functions. Its comprehensive LSIG protection makes the breaker suitable for applications requiring coordinated protection against sustained overloads, short circuits and earth faults, while adjustable protection settings support coordination with the wider electrical distribution system.
The 1SDA059245R1 uses a fixed three-pole configuration with rear horizontal terminals for permanent switchboard installation. Four auxiliary changeover contacts and circuit-breaker open/closed indication support integration with switchboard signalling and control systems, while the E1N platform provides a rated ultimate short-circuit breaking capacity of 50 kA at 400 V AC.
