Why Choose the ABB E2S 2000 PR122/P-LSIRc Air Circuit Breaker?
The ABB E2S 2000 PR122/P-LSIRc, order code 1SDA058681R1, is a SACE Emax air circuit breaker designed for switching and protection in demanding low-voltage power-distribution systems. This model combines a 2000 A rated current, three-pole configuration and PR122/P-LSIRc R2000 electronic overcurrent release.
The 1SDA058681R1 is supplied in a fixed (F) execution with horizontal rear (HR) terminals, making it suitable for permanent installation in low-voltage switchboards with rear busbar connections. It is equipped with four auxiliary contacts and circuit-breaker open/closed position indication for integration with signalling, monitoring and control circuits.
The E2S platform provides substantial fault-current performance, including an 85 kA rated ultimate short-circuit breaking capacity at 400 V AC, 50 Hz. Its PR122/P-LSIRc release combines adjustable overload and short-circuit protection with residual-current functionality, providing a comprehensive protection solution for important incoming and feeder circuits.
Key Advantages
- 2000 A rated current for high-current low-voltage distribution circuits.
- Three-pole construction for three-phase power-distribution applications.
- PR122/P-LSIRc R2000 electronic release provides comprehensive electronic protection.
- Long-time, short-time and instantaneous protection covers overload and phase short-circuit conditions.
- Rc residual-current functionality extends the protection capabilities of the electronic release.
- 85 kA ultimate short-circuit breaking capacity at 400 V AC suits installations with substantial prospective fault currents.
- Fixed construction with horizontal rear terminals is well suited to permanent switchboard installations.
- Includes four auxiliary contacts and open/closed position indication for control and signalling.

Reliable LSIRc Protection for High-Current Distribution
The PR122/P-LSIRc electronic release combines multiple protection functions for comprehensive circuit protection. Long-time protection responds to sustained overloads, short-time protection provides delayed short-circuit response to support system coordination, and instantaneous protection rapidly interrupts severe short-circuit currents. The Rc function adds residual-current protection capability to the release configuration.
Combined with the E2S breaker's 2000 A current rating and 85 kA ultimate breaking capacity at 400 V AC, the 1SDA058681R1 provides a robust solution for high-current incoming and feeder circuits. Its fixed horizontal-rear configuration is particularly suitable for permanent switchboards requiring substantial fault interruption capability, configurable electronic protection and rear busbar integration.
Typical Applications
- Main low-voltage electrical distribution switchboards.
- High-current industrial incoming circuits.
- Industrial and commercial feeder protection.
- Manufacturing and process facilities.
- Commercial building power distribution.
- Infrastructure electrical systems.
- Transformer secondary protection.
- Installations requiring electronic LSI and residual-current protection functionality.
