1SDA056108R1 ABB E2L1600 PR122/P-LSI 1600 A 4P Withdrawable Air Circuit Breaker Moving Part

Why Choose the ABB E2L1600 PR122/P-LSI Air Circuit Breaker Moving Part?

The ABB E2L1600 PR122/P-LSI, order code 1SDA056108R1, is a high-performance four-pole withdrawable air circuit breaker moving part designed for demanding low-voltage power distribution systems. Part of the ABB SACE Emax E2 series, it combines a rated current of 1600 A with the advanced PR122/P-LSI R1600 electronic overcurrent release.

The PR122/P-LSI release provides long-time, short-time and instantaneous protection, helping protect conductors, switchgear and connected equipment against sustained overloads and short-circuit conditions. Adjustable electronic protection settings support effective selectivity and coordination within industrial, commercial and infrastructure electrical distribution networks.

This version is supplied as the moving part of a withdrawable E2L1600 circuit breaker and is intended for use with the appropriate ABB SACE Emax fixed part. It features four auxiliary contacts and circuit-breaker open/closed position indication, while the E2L performance level provides an ultimate short-circuit breaking capacity of 130 kA at 400/415 V AC for demanding high-fault-level installations.

High-Breaking-Capacity LSI Protection for Critical Distribution

The ABB SACE Emax E2L1600 is designed for low-voltage installations where substantial prospective short-circuit currents require high interruption performance. Its E2L execution provides an ultimate and service short-circuit breaking capacity of 130 kA at 400/415 V AC, making it particularly suitable for main distribution boards, transformer-fed systems and demanding industrial switchgear.

The PR122/P-LSI electronic release combines long-time overload protection, short-time protection for selective fault coordination and instantaneous protection against severe short circuits. Together with the withdrawable moving-part design, four auxiliary contacts and open/closed position indication, the E2L1600 provides robust protection and practical serviceability in compatible ABB SACE Emax switchgear.

Typical Applications

• Main low-voltage electrical distribution switchboards.
• Industrial power distribution systems.
• Manufacturing and process plant switchgear.
• Commercial and infrastructure electrical distribution.
• Transformer secondary distribution systems.
• Generator and standby power installations.
• High-current incoming and feeder protection.
• Withdrawable switchgear requiring high breaking capacity and adjustable LSI protection.
