Why Choose the ABB E3V800 PR122/P-LSIG 800A 3P Fixed Air Circuit Breaker?
The ABB E3V800 PR122/P-LSIG, order code 1SDA056533R1, is a high-performance 800 A three-pole fixed air circuit breaker from the ABB SACE Emax E3 series. Designed for demanding low-voltage power distribution, this E3V configuration combines substantial short-circuit performance with the PR122/P-LSIG R800 electronic overcurrent release.
The PR122/P-LSIG release provides long-time, short-time, instantaneous and ground-fault protection, helping protect cables, busbars, transformers and connected equipment against overloads, short circuits and earth faults. Its comprehensive LSIG protection functions make this breaker suitable for coordinated distribution systems requiring adjustable electronic protection.
With a rated uninterrupted current of 800 A, a three-pole configuration and a rated voltage of 690 V AC, the E3V800 is designed for three-phase low-voltage distribution. This fixed version features rear horizontal terminals, four change-over auxiliary contacts and open/closed circuit-breaker position indication for practical switchboard integration.
