1SDA056747R1 ABB E3L2000 PR122/P-LI 2000A 4P Withdrawable Air Circuit Breaker Moving Part

Why Choose the ABB E3L2000 PR122/P-LI 2000A 4P Withdrawable Air Circuit Breaker?

The ABB E3L2000 PR122/P-LI, order code 1SDA056747R1, is a high-performance SACE Emax E3L air circuit breaker moving part designed for protection and switching in high-current low-voltage electrical distribution systems. Rated at 2000 A, this four-pole withdrawable configuration combines the proven ABB SACE Emax platform with a PR122/P-LI electronic overcurrent release.

The PR122/P-LI release provides long-time (L) and instantaneous (I) overcurrent protection, protecting electrical installations against overload and severe short-circuit conditions. The PR122/P platform also provides advanced electronic trip-unit functionality within the New Emax family, making this breaker suitable for demanding industrial, commercial and infrastructure power-distribution applications.

This configuration is supplied as the four-pole withdrawable moving part (W MP) of the E3L2000 circuit breaker and is designed for use with the appropriate SACE Emax fixed part. It has a rated operational voltage of 690 V AC and an ultimate short-circuit breaking capacity of 130 kA at 400 V AC, providing robust protection for high-capacity switchboards.

Key Advantages

• High-current 2000 A SACE Emax E3L air circuit breaker moving part.

Reliable High-Current Protection with Withdrawable Serviceability

Air circuit breakers such as the ABB SACE Emax E3L are designed to interrupt high fault currents and protect low-voltage electrical distribution equipment against damaging overcurrent conditions. The PR122/P-LI electronic release provides long-time overload and instantaneous short-circuit protection, helping safeguard feeders, busbars and downstream electrical equipment.

The withdrawable E3L2000 configuration is particularly suitable for switchboards where serviceability and operational flexibility are important. Its moving part can be disconnected and withdrawn from the corresponding fixed section for inspection or maintenance, while the 2000 A rating and high E3L breaking performance support demanding industrial power-distribution duties.

Typical Applications

• Main low-voltage electrical distribution switchboards.
• Industrial power distribution systems.
• High-current incoming and feeder protection.
• Commercial and infrastructure electrical distribution.
• Manufacturing and process-industry switchgear.
• Transformer and generator distribution systems.
• Switchboards requiring withdrawable circuit breakers for improved serviceability.
• High-capacity installations requiring four-pole switching and protection.
