1SDA058687R1 ABB E2S2000 PR122/P-LSIRc 2000A 4-Pole Withdrawable Air Circuit Breaker

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

The ABB E2S2000 PR122/P-LSIRc is a high-performance 2000 A air circuit breaker (ACB) moving portion designed for advanced protection and switching in low-voltage electrical distribution systems. As part of the proven ABB SACE Emax E2 series, this four-pole withdrawable configuration combines high-current switching capability with the PR122/P electronic trip unit for dependable protection of industrial and commercial power networks.

Equipped with LSIRc protection, the PR122/P trip unit provides long-time overload, short-time short-circuit and instantaneous short-circuit protection together with residual-current protection when used with the appropriate external toroid. This protection combination is particularly valuable where both high-current circuit protection and sensitive earth-leakage or residual-current detection are required.

With a rated current of 2000 A, the E2S2000 is engineered for demanding main distribution and feeder applications. This version is a four-pole withdrawable moving portion fitted with a PR122/P-LSIRc R2000 overcurrent release, four auxiliary contacts and open/closed circuit-breaker position indication, providing a service-friendly solution for compatible SACE Emax switchgear.

Advanced Overcurrent and Residual-Current Protection

Air circuit breakers such as the ABB E2S2000 provide switching and protection for high-current low-voltage distribution circuits. The PR122/P-LSIRc electronic release combines conventional overload and short-circuit protection with residual-current functionality, allowing the protection system to respond to a wider range of electrical fault conditions.

For residual-current operation, the PR122/P-LSIRc configuration is used with the appropriate toroid for residual-current measurement. Combined with the withdrawable construction, this makes the breaker well suited to critical switchgear where comprehensive protection, maintainability and continuity of service are important.

Typical Applications

• Main low-voltage distribution switchboards.
• Industrial power distribution systems.
• Manufacturing and process plants.
• Commercial and infrastructure electrical installations.
• Withdrawable switchgear and power distribution centres.
• Transformer secondary and high-current feeder protection.
• Generator and utility distribution systems.
• Circuits requiring residual-current as well as overcurrent protection.
