Why Choose the ABB E2S 800 PR121/P-LSIG 1SDA058300R1 Air Circuit Breaker?
The ABB 1SDA058300R1 is a high-performance SACE Emax E2S 800 air circuit breaker moving part designed for switching and protection in demanding low-voltage power distribution systems. Rated at 800 A, this three-pole withdrawable configuration combines the E2S breaker platform with the PR121/P-LSIG electronic overcurrent release.
The PR121/P-LSIG provides long-time, short-time, instantaneous and ground-fault protection, giving the breaker comprehensive protection against overloads, short circuits and earth-fault conditions. These LSIG functions make the E2S 800 suitable for industrial and commercial distribution systems where selective electronic protection and dependable fault interruption are required.
This configuration is a three-pole withdrawable moving part with a rated current of 800 A. Its withdrawable construction is designed for use with the corresponding compatible fixed part, allowing the breaker moving part to be isolated and withdrawn from the switchgear for inspection, maintenance or replacement while supporting demanding power distribution applications.
