1SDA056613R1 ABB E3V 1600 PR122/P-LSIG 1600 A Air Circuit Breaker

Why Choose the ABB 1SDA056613R1 E3V 1600 Air Circuit Breaker?

The ABB 1SDA056613R1 is a high-performance SACE Emax E3V air circuit breaker moving part designed for protection and switching in demanding low-voltage electrical distribution systems. Configured as an E3V 1600 PR122/P-LSIG, this three-pole withdrawable unit combines a rated uninterrupted current of 1600 A with ABB's PR122/P electronic overcurrent release.

As part of the ABB SACE Emax series, the E3V 1600 is engineered for installations requiring high short-circuit performance, selective protection and dependable operation. The PR122/P-LSIG release provides long-time, short-time, instantaneous and ground-fault protection functions, helping protect electrical installations against overloads, short circuits and earth faults while supporting coordinated protection throughout the distribution system.

This configuration is a three-pole withdrawable moving part with a rated operational voltage of 690 V AC. The E3V performance level provides an ultimate short-circuit breaking capacity of 130 kA at 220–440 V AC and 100 kA at 500–690 V AC, making it suitable for high-fault-level industrial switchboards and critical power distribution systems.

Comprehensive Protection for High-Performance Power Distribution

Air circuit breakers such as the ABB SACE Emax E3V provide switching and protection for low-voltage electrical distribution systems where substantial prospective fault currents can occur. The E3V 1600 combines a 1600 A current rating with high short-circuit interruption capability, helping protect switchboards, busbars, cables and connected equipment against damaging overload, short-circuit and earth-fault conditions.

The PR122/P-LSIG electronic trip unit combines long-time overload, short-time selective short-circuit, instantaneous short-circuit and ground-fault protection. These functions provide comprehensive protection for critical distribution circuits, while the withdrawable construction allows the breaker moving part to be isolated and removed from compatible switchgear for inspection, servicing and maintenance.

Typical Applications

• Main incoming circuit protection in low-voltage switchboards.
• Industrial power distribution systems.
• High-fault-level distribution feeders.
• Manufacturing and process plant electrical systems.
• Commercial and infrastructure power distribution.
• Generator and transformer distribution systems.
• Critical circuits requiring comprehensive LSIG electronic protection.
• Withdrawable switchgear requiring maintainable high-performance 1600 A circuit protection.
