1SDA057987R1 ABB E4V-A 3600 PR122/P-LI 3600 A 3-Pole Fixed Air Circuit Breaker

Why Choose the ABB E4V-A 3600 PR122/P-LI Air Circuit Breaker?

The ABB 1SDA057987R1 is a high-performance SACE Emax E4V-A 3600 air circuit breaker (ACB) designed for protection and switching of high-current low-voltage electrical distribution systems. Part of the ABB New Emax range, this fixed three-pole circuit breaker combines a 3600 A rated current with the electronic PR122/P-LI overcurrent release for dependable overload and instantaneous short-circuit protection.

The E4V-A performance level is engineered for demanding industrial and commercial power distribution applications requiring robust circuit protection and reliable switching. Its PR122/P electronic trip unit provides Long-time and Instantaneous protection functions, identified by the LI designation, helping protect conductors, switchgear and connected equipment against sustained overloads and severe short-circuit faults.

With a rated current of 3600 A and a three-pole fixed configuration, the E4V-A 3600 is suited to substantial low-voltage distribution installations. ABB order code 1SDA057987R1 identifies the fixed UL version equipped with a PR122/P-LI R3600 overcurrent release, Im 54000 A designation and horizontal rear terminals.

Reliable Circuit Protection for High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax E4V-A protect low-voltage distribution systems against damaging overcurrents while also providing controlled switching of high-current electrical circuits. Their robust construction and electronic protection make them particularly suitable for main incomers, bus-section applications and high-current feeders in industrial and commercial switchgear.

The PR122/P-LI electronic trip unit provides Long-time and Instantaneous protection. Long-time protection responds to sustained overload conditions that could cause excessive heating of conductors and equipment, while Instantaneous protection provides rapid intervention when severe short-circuit currents are detected.

Typical Applications

• Main incoming circuit protection in low-voltage switchboards.
• Industrial power distribution systems.
• High-current feeder protection.
• Power distribution and switchgear assemblies.
• Manufacturing plants and process facilities.
• Commercial buildings, infrastructure and large electrical installations.
