1SDA059225R1 ABB E1N1000 PR122/P-LI 1000 A 3-Pole Fixed Air Circuit Breaker

Why Choose the ABB 1SDA059225R1 E1N1000 Air Circuit Breaker?

The ABB 1SDA059225R1 is a high-performance SACE Emax E1N 1000 A three-pole air circuit breaker designed for reliable protection and switching in low-voltage electrical distribution systems. As part of the ABB New Emax product family, this fixed circuit breaker combines robust construction with a PR122/P-LI electronic overcurrent release for dependable protection of industrial and commercial electrical installations.

The E1N1000 provides a 1000 A rated current in a three-pole fixed configuration with rear horizontal terminals. Its PR122/P-LI electronic trip unit provides long-time and instantaneous overcurrent protection, helping protect electrical distribution equipment against overload and short-circuit conditions.

With a rated operational voltage of up to 690 V AC and rated service and ultimate short-circuit breaking capacities of 50 kA across its specified AC voltage range, the 1SDA059225R1 is suitable for demanding low-voltage power distribution applications. Four auxiliary contacts and open/closed position indication support integration with switchboard control, signalling and monitoring systems.
