Why Choose the ABB E2S 800 PR123/P-LSIG 800 A 4-Pole Air Circuit Breaker?
The ABB E2S 800 PR123/P-LSIG, order code 1SDA058297R1, is a four-pole fixed SACE Emax air circuit breaker rated at 800 A. It combines the E2 frame and S performance class with the advanced PR123/P-LSIG electronic overcurrent release for comprehensive protection and monitoring in demanding low-voltage power-distribution systems.
The PR123/P-LSIG release provides long-time overload (L), short-time short-circuit (S), instantaneous short-circuit (I) and ground-fault (G) protection. This LSIG combination provides comprehensive protection against overloads, short circuits and qualifying earth faults while supporting coordinated protection within complex distribution networks.
This configuration is a fixed four-pole breaker with rear horizontal terminals. It is supplied with the PR123/P-LSIG R800 overcurrent release and four auxiliary contacts with open/closed position indication, making it well suited to main distribution and feeder applications requiring high-performance protection and breaker-status signalling.
Key Advantages
- 800 A rated current for substantial low-voltage distribution loads.
- Four-pole construction for three-phase systems incorporating a neutral conductor.
- Advanced PR123/P-LSIG electronic protection release.
- Provides comprehensive L, S, I and G protection functions.
- Fixed circuit-breaker configuration for permanent switchboard installation.
- Rear horizontal terminals support practical busbar integration.
- E2S performance class provides high short-circuit interruption capability.
