1SDA056037R1 ABB E2S2000 PR122/P-LSIG 2000 A 3-Pole Withdrawable Air Circuit Breaker

Why Choose the ABB E2S2000 PR122/P-LSIG 1SDA056037R1 Air Circuit Breaker?

The ABB 1SDA056037R1 is a high-performance SACE Emax E2S2000 air circuit breaker moving part designed for reliable switching and protection in demanding low-voltage electrical distribution systems. As part of the ABB New Emax product range, this three-pole withdrawable circuit breaker has a rated uninterrupted current of 2000 A and incorporates the PR122/P-LSIG electronic overcurrent release.

The PR122/P-LSIG trip unit provides comprehensive long-time, short-time, instantaneous and earth-fault protection, helping protect electrical installations against overloads, short circuits and earth faults. Its electronic protection functionality makes the E2S2000 suitable for industrial and commercial distribution systems where dependable protection, selectivity and monitoring are required.

With a rated operational voltage of up to 690 V AC, three-pole configuration and withdrawable W moving-part design, the E2S2000 is well suited to high-current switchboards where serviceability and operational flexibility are important. The E2S performance class provides a rated ultimate short-circuit breaking capacity of 85 kA at 400 V AC, while the withdrawable construction allows the moving part to be isolated and removed from its compatible fixed part for maintenance.
