Why Choose the ABB E4S4000 PR122/P-LSI Air Circuit Breaker?
The ABB E4S4000 PR122/P-LSI, order code 1SDA056796R1, is a high-current SACE Emax air circuit breaker (ACB) designed for switching and overcurrent protection in demanding low-voltage power-distribution systems. Part of the ABB SACE Emax E4 series, this four-pole fixed circuit breaker combines a 4000 A rated uninterrupted current with the PR122/P-LSI R4000 electronic overcurrent release.
The PR122/P-LSI release provides long-time overload, short-time short-circuit and instantaneous short-circuit protection. These LSI functions allow the breaker to protect high-current conductors, switchboards and downstream equipment against sustained overloads and short circuits while supporting selective coordination within complex industrial and infrastructure distribution networks.
This configuration is a four-pole fixed circuit breaker with rear flat horizontal terminals. Rated for operation up to 690 V AC, the E4S4000 provides an ultimate short-circuit breaking capacity of 75 kA across its specified AC voltage range and is fitted with four auxiliary contacts plus circuit-breaker open/closed position indication.

Reliable LSI Protection for 4000 A Power Distribution
The ABB SACE Emax E4S4000 is engineered for switching and protection at main incomer, bus-coupler and high-current feeder levels within substantial low-voltage distribution systems. Its PR122/P-LSI electronic release provides long-time protection against sustained overloads, short-time protection for coordinated fault clearing and instantaneous intervention against severe short-circuit currents.
The combination of a 4000 A current rating, four-pole construction and 75 kA short-circuit capability makes the 1SDA056796R1 suitable for major industrial and infrastructure switchboards. Its fixed construction and rear flat horizontal terminals support permanent busbar integration, while the auxiliary contacts provide circuit-breaker status information for associated monitoring, signalling and control systems.
Typical Applications
- Main low-voltage distribution switchboards.
- High-current industrial power-distribution systems.
- Manufacturing and process plants.
- Commercial and infrastructure electrical installations.
- Transformer secondary and main incomer protection.
- High-current feeder and bus-coupler applications.
- Power distribution and control assemblies.
