1SDA057349R1 ABB E2N-A 1600 PR122/P-LI 1600 A 3-Pole Withdrawable Air Circuit Breaker

Why Choose the ABB E2N-A 1600 PR122/P-LI 1600 A Air Circuit Breaker?

The ABB E2N-A 1600 PR122/P-LI, order code 1SDA057349R1, is a SACE Emax E2N-A air circuit breaker moving part designed for protection, switching and isolation in demanding low-voltage power distribution systems. Rated at 1600 A, this three-pole withdrawable unit combines ABB's E2N-A platform with a PR122/P-LI R1600 electronic overcurrent release.

This UL configuration forms part of the ABB SACE Emax family and is intended for industrial switchboards, power distribution systems and infrastructure applications requiring dependable electronic overcurrent protection. The PR122/P-LI release provides long-time overload and instantaneous short-circuit protection for important incoming and feeder circuits.

The breaker is supplied as a three-pole withdrawable moving part with an Im 24000 A configuration. It is fitted with four auxiliary contacts and open/closed position indication, while its draw-out construction supports efficient inspection, servicing and replacement within a compatible ABB SACE Emax fixed part.
