Why Choose the ABB E3S2500 PR122/P-LSIG 2500A 4P Fixed Air Circuit Breaker?
The ABB 1SDA056285R1 is a high-performance SACE Emax E3S air circuit breaker (ACB) designed for switching and comprehensive protection in demanding low-voltage electrical distribution systems. Part of the ABB New Emax product group, this four-pole fixed circuit breaker combines a 2500 A rated uninterrupted current with the advanced PR122/P-LSIG R2500 electronic overcurrent release for industrial, commercial and infrastructure power networks.
The E3S2500 provides long-time, short-time, instantaneous and earth-fault protection through its LSIG trip functionality. The PR122/P electronic release protects against overload, short-time delayed short-circuit, instantaneous short-circuit and earth-fault conditions while providing the advanced measurement, signalling and accessory capabilities associated with ABB's PR122/P platform.
With a rated uninterrupted current of 2500 A and an ultimate short-circuit breaking capacity of 75 kA at 415 V AC, the E3S2500 provides robust protection for high-capacity distribution systems. This version features a four-pole fixed configuration with rear horizontal terminals, four auxiliary contacts and circuit-breaker open/closed position indication for permanent integration into low-voltage switchgear.
