Why Choose the ABB E2S 800 PR122/P-LSIG 800 A 4-Pole Air Circuit Breaker?
The ABB E2S 800 PR122/P-LSIG, order code 1SDA058295R1, is a four-pole fixed SACE Emax air circuit breaker rated at 800 A. It combines the E2 frame with S-class short-circuit performance and the advanced PR122/P-LSIG electronic protection release for demanding low-voltage power-distribution applications.
The PR122/P-LSIG release provides long-time overload (L), short-time short-circuit (S), instantaneous short-circuit (I) and ground-fault (G) protection. This comprehensive protection combination makes the breaker suitable for installations requiring selective overcurrent protection together with earth-fault protection.
This configuration is a fixed four-pole breaker with rear horizontal terminals and includes four auxiliary contacts for open/closed breaker-position indication. The E2S platform provides a rated ultimate short-circuit breaking capacity of up to 85 kA at common low-voltage system voltages through 440 V AC.
Key Advantages
- 800 A rated current for substantial low-voltage distribution loads.
- Four-pole construction for switching and protecting three-phase systems with neutral.
- Advanced PR122/P-LSIG electronic trip unit.
- Provides L, S, I and G protection functions.
- Fixed circuit-breaker construction.
- Rear horizontal terminals for switchboard busbar integration.
- High E2S short-circuit performance for demanding distribution systems.
- Four auxiliary contacts provide open/closed breaker-position indication.
Key Features
- SACE Emax E2S 800 air circuit breaker.
- Rated current In = 800 A.
- 4-pole configuration.
- PR122/P-LSIG electronic overcurrent release.
- Long-time (L) overload protection.
- Short-time (S) short-circuit protection.
- Instantaneous (I) short-circuit protection.
- Ground-fault (G) protection.
- Fixed breaker with rear horizontal terminals.
- Designed to IEC requirements for low-voltage air circuit breakers.
Advanced LSIG Protection for Critical Power Distribution
The PR122/P-LSIG release provides a comprehensive electronic protection package. Long-time protection responds to sustained overloads, short-time protection supports selective coordination during high-current faults, instantaneous protection provides rapid response to severe short circuits, and ground-fault protection detects qualifying earth-fault currents.
Combined with the E2S breaker's high short-circuit performance and four-pole architecture, these functions make the ABB 1SDA058295R1 well suited to main distribution, feeder and other critical protection duties where dependable fault interruption and coordinated protection are required.
Typical Applications
- Main low-voltage distribution switchboards.
- Industrial power-distribution systems.
- Commercial and infrastructure switchgear.
- Four-wire three-phase electrical systems.
- Main incomer and high-current feeder protection.
- Installations requiring ground-fault protection.
- Selective and coordinated low-voltage protection systems.
