1SDA056647R1 ABB E3V2000 PR123/P-LSIG 2000A 3P Withdrawable Air Circuit Breaker

Why Choose the ABB E3V2000 PR123/P-LSIG 2000A 3P Withdrawable Air Circuit Breaker?

The ABB E3V2000 PR123/P-LSIG, order code 1SDA056647R1, is a high-performance SACE Emax air circuit breaker (ACB) moving part designed for advanced protection and switching in demanding low-voltage power distribution systems. Part of the ABB SACE Emax E3 series, this three-pole withdrawable breaker combines a 2000 A rated uninterrupted current with the sophisticated PR123/P-LSIG R2000 electronic overcurrent release.

The E3V2000 is supplied as the moving part for a withdrawable three-pole installation, enabling convenient removal from the associated fixed part for inspection, servicing and maintenance. Its PR123/P-LSIG electronic release provides long-time, short-time, instantaneous and earth-fault protection, delivering comprehensive protection against overloads, short circuits and earth-fault conditions.

With a rated uninterrupted current of 2000 A and an ultimate short-circuit breaking capacity of 130 kA at 400 V AC, 50 Hz, the E3V2000 is suited to installations with demanding prospective fault levels. The breaker also incorporates 2 NO + 2 NC auxiliary contacts, open/closed position indication and integrated trip indication for effective switchboard monitoring and control.
