1SDA057115R1 ABB E6V5000PR122/P-LI 5000 A 4-Pole Fixed Air Circuit Breaker

Why Choose the ABB E6V5000PR122/P-LI 5000 A Air Circuit Breaker?

The ABB E6V5000PR122/P-LI, order code 1SDA057115R1, is a high-performance SACE Emax E6 V air circuit breaker designed for protection, switching and isolation in demanding low-voltage power distribution systems. Rated at 5000 A, this four-pole fixed breaker combines ABB's E6 V high-breaking-capacity platform with the advanced PR122/P-LI electronic overcurrent release.

As part of the ABB SACE Emax range, the breaker is engineered for industrial switchboards, power distribution centres and critical infrastructure where substantial current capacity and high fault-interruption performance are required. The PR122/P-LI trip unit provides long-time overload and instantaneous short-circuit protection for high-current distribution circuits.

This configuration is a four-pole fixed circuit breaker with horizontal rear terminals and a rated current of 5000 A. The E6 V performance level provides a rated ultimate short-circuit breaking capacity of 150 kA at 415 V AC and a rated short-time withstand current of 100 kA for 1 s, making it suitable for installations with exceptionally high prospective fault levels.
