1SDA056035R1 ABB E2S2000 PR122/P-LI 2000A 3-Pole Withdrawable Air Circuit Breaker

Why Choose the ABB E2S2000 PR122/P-LI 2000A Air Circuit Breaker?

The ABB E2S2000 PR122/P-LI, order code 1SDA056035R1, is a high-performance three-pole withdrawable air circuit breaker moving part designed for switching and protection in demanding low-voltage electrical distribution systems. Part of the established ABB SACE Emax series, this E2S circuit breaker combines a rated current of 2000 A with the PR122/P electronic overcurrent release for dependable protection in industrial, commercial and infrastructure power networks.

This configuration is supplied as the withdrawable moving part (W MP) for use with the corresponding SACE Emax withdrawable fixed part. The fitted PR122/P-LI R2000 electronic overcurrent release provides long-time and instantaneous protection functions, helping protect electrical systems against sustained overloads and severe short-circuit faults while offering the maintenance flexibility associated with withdrawable switchgear.

The E2S performance level provides strong short-circuit interruption capability for high-current distribution applications. The breaker is supplied with four auxiliary contacts and open/closed position indication, supporting circuit-breaker status signalling, monitoring and integration into sophisticated low-voltage switchboards.

Advanced Protection for Low-Voltage Power Distribution

Air circuit breakers such as the ABB SACE Emax E2S2000 provide switching, isolation and protection for high-current low-voltage distribution circuits. The E2S performance class combines high short-circuit interruption capability with robust fault-current withstand performance, while the withdrawable architecture enables the moving circuit-breaker assembly to be removed from its compatible fixed part for inspection, servicing or replacement.

The PR122/P electronic overcurrent release provides LI protection for demanding electrical networks. Long-time protection responds to sustained overload conditions, while instantaneous protection rapidly interrupts severe short-circuit currents to help safeguard conductors, switchgear, transformers and connected electrical equipment.

Typical Applications

• Low-voltage main distribution switchboards.
• Industrial power distribution systems.
• Main incomer and high-current feeder protection.
• Manufacturing and process plants.
• Commercial buildings and infrastructure installations.
• Motor control centres and power distribution assemblies.
• Transformer secondary and generator distribution circuits.
• Switchgear requiring withdrawable circuit-breaker architecture for maintenance flexibility.
