1SDA061031R1 ABB E2S-A 800 PR122/P-LSIG 800A 3P Fixed Air Circuit Breaker

Why Choose the ABB E2S-A 800 PR122/P-LSIG 800A 3P Air Circuit Breaker?

The ABB E2S-A 800 PR122/P-LSIG, order code 1SDA061031R1, is a high-performance SACE Emax air circuit breaker designed for protection and switching in demanding low-voltage power-distribution systems. Rated at 800 A, this three-pole E2S-A breaker combines robust power-circuit protection with ABB's advanced PR122/P-LSIG electronic overcurrent release.

This specific configuration is a fixed version with rear horizontal terminals and an R800 rating plug. The PR122/P-LSIG release provides long-time, short-time, instantaneous and earth-fault protection functions, delivering comprehensive LSIG protection against overloads, short circuits and earth faults while supporting coordinated protection within industrial distribution networks.

Designed as a UL SACE Emax circuit breaker, the 1SDA061031R1 is fitted with four auxiliary contacts and open/closed position indication for integration into switchboard monitoring and control systems. Its fixed construction and rear horizontal connections make it well suited to permanent installation in compatible low-voltage switchgear and power-distribution assemblies.
