Why Choose the ABB 1SDA060755R1 E3S-A 800 PR121/P-LI Air Circuit Breaker?
The ABB 1SDA060755R1, identified as E3S-A 800 PR121/P-LI In=800A 3p F HR, is a three-pole fixed SACE Emax air circuit breaker designed for dependable protection and switching in demanding low-voltage power-distribution systems. This UL configuration combines the E3S-A frame with an 800 A rated current and 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. An R800 rating plug matches the breaker’s 800 A current rating, providing an integrated protection solution for industrial, commercial and infrastructure distribution systems.
The breaker is supplied in a three-pole fixed execution with horizontal rear terminals. The E3S-A 800 platform has a 65 kA short-circuit current rating at 480 V and a 65 kA short-time current rating, providing substantial fault-handling capability for high-performance low-voltage switchboards.
