1SDA056603R1 ABB E3V1600 PR122/P-LI 1600A 4P Fixed Air Circuit Breaker

Why Choose the ABB E3V1600 PR122/P-LI 1600A 4P Fixed Air Circuit Breaker?

The ABB E3V1600 PR122/P-LI, order code 1SDA056603R1, is a high-performance SACE Emax air circuit breaker (ACB) designed for switching and overcurrent protection in demanding low-voltage power distribution systems. As part of the ABB SACE Emax E3 series, this four-pole fixed circuit breaker combines a 1600 A current rating with the PR122/P-LI R1600 electronic overcurrent release.

This E3V breaker is supplied in a fixed four-pole configuration with horizontal rear terminals, making it suitable for integration into industrial switchboards and power distribution assemblies. The PR122/P-LI electronic release provides long-time overload and instantaneous short-circuit protection, while four auxiliary contacts provide open/closed circuit-breaker position indication for monitoring and control applications.

With a rated uninterrupted current of 1600 A, rated operational voltage of 690 V AC and an ultimate short-circuit breaking capacity of 130 kA at 415 V AC, the E3V1600 is engineered for high-current installations with demanding prospective fault levels. Its rated short-time withstand current of 85 kA for 1 s further supports dependable performance in heavy-duty electrical distribution systems.
