1SDA056019R1 ABB E2S2000 PR122/P-LI 2000A 3-Pole Fixed Air Circuit Breaker

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

The ABB E2S2000 PR122/P-LI, order code 1SDA056019R1, is a high-performance three-pole fixed air circuit breaker (ACB) 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 a fixed three-pole circuit breaker with horizontal rear terminals. 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 providing a robust solution for high-current switchboard applications.

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, monitoring and integration into low-voltage power distribution assemblies.

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, making this breaker suitable for main distribution boards, incomers, feeders and other critical positions where substantial prospective fault currents may be present.

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.
• High fault-level low-voltage switchgear systems.
