Why Choose the ABB E2S 800 PR122/P-LSI 800 A 4-Pole Withdrawable Air Circuit Breaker?
The ABB E2S 800 PR122/P-LSI, order code 1SDA058310R1, is the moving part of a four-pole withdrawable SACE Emax air circuit breaker rated at 800 A. It combines the E2 frame and S performance class with a PR122/P-LSI R800 electronic overcurrent release for dependable protection of demanding low-voltage power-distribution systems.
The PR122/P-LSI release provides long-time overload (L), short-time short-circuit (S) and instantaneous short-circuit (I) protection. This combination supports effective overload protection, selective coordination during short-circuit conditions and rapid interruption of severe faults.
The W MP configuration identifies this product as a withdrawable moving part for use with the appropriate SACE Emax E2 fixed part. It is also fitted with four auxiliary contacts and provides circuit-breaker open/closed position indication, supporting integration into switchboard monitoring and control systems.
Key Advantages
- 800 A rated current for substantial low-voltage distribution loads.
- Four-pole construction for three-phase systems incorporating a neutral conductor.
- Advanced PR122/P-LSI R800 electronic overcurrent release.
- Provides long-time, short-time and instantaneous protection functions.
- Withdrawable moving-part construction supports maintenance and breaker replacement.
- E2S performance class provides high short-circuit interruption capability.
- Four auxiliary contacts support breaker-status signalling.
- Open/closed circuit-breaker position indication is provided.
Key Features
- SACE Emax E2S 800 air circuit breaker moving part.
- Rated current In = 800 A.
- 4-pole configuration.
- PR122/P-LSI R800 electronic overcurrent release.
- Long-time (L) overload protection.
- Short-time (S) short-circuit protection.
- Instantaneous (I) short-circuit protection.
- Withdrawable (W) version.
- Moving part (MP) configuration.
- Four auxiliary contacts with open/closed position indication.
Advanced LSI Protection with Withdrawable Emax Architecture
The PR122/P-LSI electronic release provides three complementary overcurrent protection functions. Long-time protection responds to sustained overloads, short-time protection provides a configurable response to short-circuit currents and can assist with selective coordination, while instantaneous protection rapidly disconnects severe short-circuit faults.
Combined with the E2S breaker's 85 kA breaking capacity at 400 V AC, four-pole architecture and withdrawable moving-part design, the ABB 1SDA058310R1 is well suited to switchgear where dependable protection, selective fault management and service-friendly circuit-breaker construction are required.
Typical Applications
- Main low-voltage distribution switchboards.
- Industrial power-distribution systems.
- Commercial and infrastructure switchgear.
- Three-phase four-wire electrical systems.
- Main incomer and high-current feeder protection.
- Withdrawable switchgear requiring convenient breaker servicing.
- Applications requiring coordinated LSI overcurrent protection.
