Why Choose the ABB E3S2000 PR122/P-LI 2000A 4P Withdrawable Air Circuit Breaker?
The ABB 1SDA056267R1 is a high-performance SACE Emax E3S air circuit breaker (ACB) moving part designed for switching and protection in demanding low-voltage electrical distribution systems. Part of the ABB New Emax product group, this four-pole withdrawable circuit breaker combines a 2000 A rated uninterrupted current with the advanced PR122/P-LI R2000 electronic overcurrent release for dependable protection of industrial, commercial and infrastructure power networks.
The E3S2000 provides long-time and instantaneous protection through its LI trip functionality. The PR122/P electronic release protects against overload and instantaneous short-circuit conditions while providing the enhanced measurement, signalling and accessory capabilities associated with ABB's PR122/P platform. As an LI configuration, it does not include short-time delayed or integrated earth-fault protection.
With a rated uninterrupted current of 2000 A, a 690 V AC rated operational voltage and an ultimate short-circuit breaking capacity of 75 kA across the specified 220–690 V AC range, the E3S2000 provides robust protection for high-capacity distribution systems. This version is supplied as a four-pole withdrawable moving part with four auxiliary contacts and open/closed position indication, allowing removal from a compatible ABB SACE Emax fixed part for inspection, testing, servicing or replacement.
