1SDA056085R1 ABB E2L1600 PR122/P-LSIG 1600A 3P Fixed Air Circuit Breaker

Why Choose the ABB E2L1600 PR122/P-LSIG 1600A 3P Fixed Air Circuit Breaker?

The ABB 1SDA056085R1 is a high-performance SACE Emax E2L air circuit breaker (ACB) designed for protection and switching in demanding low-voltage electrical distribution systems. Part of the ABB New Emax product group, this three-pole fixed circuit breaker combines a 1600 A rated uninterrupted current with the advanced PR122/P-LSIG electronic overcurrent release for comprehensive protection of industrial, commercial and infrastructure power networks.

The E2L1600 provides long-time, short-time, instantaneous and earth-fault protection through its LSIG trip functionality. The PR122/P electronic release provides sophisticated protection and measurement capabilities, helping safeguard conductors, switchgear and connected equipment against overloads, short circuits and earth faults while supporting effective coordination and selectivity across the electrical distribution system.

With a rated uninterrupted current of 1600 A and an ultimate short-circuit breaking capacity of 130 kA at 400/415 V AC, the E2L1600 is particularly suitable for installations with high prospective fault currents. This version features a three-pole fixed configuration with rear horizontal terminals, four auxiliary contacts and circuit-breaker open/closed position indication for permanent integration into low-voltage switchboards.

Reliable High-Capacity Protection for Low-Voltage Power Distribution

Air circuit breakers such as the ABB SACE Emax E2L1600 provide switching, isolation and comprehensive overcurrent protection at critical points within high-current low-voltage distribution systems. The E2L performance level is designed for installations requiring exceptionally high short-circuit interruption capability, making it particularly suitable for switchboards supplied by large transformers, generators and other sources capable of producing substantial prospective fault currents.

The PR122/P-LSIG electronic trip unit provides long-time overload, short-time overcurrent, instantaneous short-circuit and earth-fault protection. Its adjustable protection characteristics allow the breaker to be coordinated with other protective devices throughout the network, helping isolate electrical faults while maintaining continuity of supply to unaffected circuits.

Typical Applications

• Main incoming circuit breakers in low-voltage switchboards.
• Industrial power distribution systems.
• Commercial and infrastructure electrical installations.
• Manufacturing and process plants.
• Transformer-fed distribution systems.
• Generator distribution and protection systems.
• High-fault-level electrical networks.
• High-current feeder protection and fixed switchgear assemblies.
