Why Choose the ABB E3N-A 2500 PR122/P-LSIG 2500A 3P Fixed Air Circuit Breaker?
The ABB E3N-A 2500 PR122/P-LSIG, order code 1SDA057419R1, is a high-current SACE Emax air circuit breaker (ACB) designed for protection, switching and isolation in demanding low-voltage power distribution systems. This three-pole fixed circuit breaker has a rated current of 2500 A and uses rear horizontal terminals for permanent integration into compatible switchgear assemblies.
The breaker is equipped with an ABB PR122/P-LSIG electronic overcurrent release and an R2500 rating plug. It provides long-time, short-time, instantaneous and ground-fault protection, giving comprehensive protection against overload, short-circuit and earth-fault conditions while supporting coordinated protection within complex electrical distribution networks.
The E3N-A 2500 combines its 2500 A current rating with ABB's N performance level and a 50 kA short-circuit rating at 480 V AC. Its fixed construction, rear horizontal terminals, four auxiliary contacts and open/closed breaker position indication make it particularly suitable for main incomers, high-current feeders and critical industrial distribution circuits.
