Why Choose the ABB 1SDA060787R1 E3H-A 800 PR121/P-LI Air Circuit Breaker?
The ABB 1SDA060787R1, identified as E3H-A 800 PR121/P-LI In=800A 3p F H, is a three-pole fixed SACE Emax air circuit breaker designed for demanding low-voltage power-distribution applications. Built on the high-performance E3H-A frame, it combines an 800 A rated current with ABB’s PR121/P electronic overcurrent release.
The fitted PR121/P-LI electronic trip unit provides long-time overload protection and instantaneous short-circuit protection. This LI protection combination provides electronic monitoring and tripping for sustained overcurrent and severe fault conditions, supporting reliable protection of industrial and commercial distribution circuits.
The breaker is supplied in a three-pole fixed execution, making it suitable for permanent integration within low-voltage switchboards. The E3H-A designation identifies the higher-performance E3 breaking-capacity version, while the 800 A current rating makes this configuration suitable for substantial main and feeder circuits.
