Why Choose the ABB 1SDA060727R1 E3S-A 3200 PR121/P-LSI Air Circuit Breaker?
The ABB 1SDA060727R1, identified as E3S-A 3200 PR121/P-LSI In=3200 3p F, is a three-pole fixed SACE Emax air circuit breaker designed for high-current low-voltage power-distribution applications. Based on the E3S-A frame, it provides a substantial 3200 A rated current together with ABB’s PR121/P electronic overcurrent protection.
The fitted PR121/P-LSI electronic trip unit provides long-time, short-time and instantaneous protection functions. This combination protects distribution circuits against overload and short-circuit conditions while providing the adjustable electronic protection required for coordinated industrial and commercial power systems.
This UL configuration is supplied in a three-pole fixed execution with rear terminals and a 3200 A rating plug. Its permanently installed design makes it well suited to main and feeder positions in switchboards where high current capacity, electronic protection and robust ABB SACE Emax construction are required.
