1SDA060883R1 ABB E3V-A 3200 PR121/P-LI 3200 A 3-Pole Fixed Air Circuit Breaker

Why Choose the ABB E3V-A 3200 PR121/P-LI 1SDA060883R1 Air Circuit Breaker?

The ABB E3V-A 3200 PR121/P-LI, order code 1SDA060883R1, is a high-performance SACE Emax air circuit breaker (ACB) designed for protection and switching in demanding low-voltage electrical distribution systems. As part of the ABB New Emax E3 series, it combines a substantial 3200 A rated current with high short-circuit performance for industrial and commercial power distribution.

This three-pole circuit breaker is equipped with an ABB PR121/P-LI electronic overcurrent release, providing long-time overload and instantaneous short-circuit protection. The electronic trip unit delivers dependable circuit protection, while the E3V-A performance level provides a 125 kA short-circuit current rating at 480 V AC and an 85 kA short-time current rating.

With a rated current of 3200 A, a three-pole fixed configuration and vertical rear terminals, the E3V-A 3200 is engineered for robust integration into high-current low-voltage switchboards. Its fixed construction, high breaking performance and electronic LI protection make it particularly suitable for critical distribution systems with demanding fault-current requirements.

High-Performance Circuit Protection for Power Distribution

Air circuit breakers such as the ABB SACE Emax E3V-A provide switching and protection for high-current low-voltage distribution circuits. By combining a robust circuit-breaking mechanism with an electronic protection release, the breaker can detect abnormal electrical conditions and disconnect the affected circuit to protect conductors, switchgear and connected equipment.

The PR121/P-LI trip unit provides long-time protection against sustained overload conditions together with instantaneous protection against severe short-circuit currents. Combined with the high breaking performance and 3200 A current rating of the E3V-A frame, this makes the breaker particularly suitable for major distribution circuits and installations with demanding fault-current requirements.

Typical Applications

• Industrial low-voltage switchboards and distribution panels.
• Main incoming circuit protection.
• High-current and high fault-level electrical distribution systems.
• Power distribution in manufacturing and processing facilities.
• Commercial and infrastructure electrical installations.
• Protection of high-current feeders and distribution circuits.
• Low-voltage switchgear requiring high-performance electronic LI protection.
