1SDA056036R1 ABB E2S2000 PR122/P-LSI 2000A 3-Pole Withdrawable Air Circuit Breaker

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

The ABB E2S2000 PR122/P-LSI, order code 1SDA056036R1, 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-LSI R2000 electronic overcurrent release provides long-time, short-time and instantaneous protection functions, helping protect electrical systems against sustained overloads and short-circuit faults while supporting selective protection coordination.

The E2S performance level provides an ultimate and service short-circuit breaking capacity of 85 kA at 415 V AC and 65 kA at 690 V AC, together with a short-time withstand current of 65 kA for 1 s. Four auxiliary contacts and open/closed circuit-breaker position indication support status signalling and monitoring, while the withdrawable design provides additional flexibility for switchboard inspection and maintenance.

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 short-time 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 LSI protection for demanding electrical networks. Long-time protection responds to sustained overload conditions, short-time protection supports selective coordination during fault events, and 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 architecture and selective overcurrent protection.
