1SDA056004R1 ABB E2S1600 1600 A 3-Pole Withdrawable Air Circuit Breaker

Why Choose the ABB E2S1600 1SDA056004R1 Air Circuit Breaker?

The ABB E2S1600 1SDA056004R1 is a high-performance SACE Emax air circuit breaker (ACB) moving part designed for protection and switching in high-current low-voltage electrical distribution systems. Part of the proven ABB SACE Emax E2 series, this three-pole withdrawable breaker combines a 1600 A rated current with the advanced PR122/P-LSI electronic trip unit for dependable overload, short-time and instantaneous short-circuit protection.

Designed for demanding industrial and commercial power distribution applications, the E2S1600 provides reliable circuit protection while its withdrawable construction supports convenient inspection, servicing and replacement when installed with the appropriate Emax fixed part. The PR122/P-LSI electronic overcurrent release provides L, S and I protection functions, supporting selective coordination and effective protection against overload and short-circuit conditions.

This model is a three-pole withdrawable moving part rated at 1600 A. The E2S performance class provides a rated ultimate short-circuit breaking capacity of 85 kA at 415 V AC, making it suitable for substantial industrial and commercial distribution systems where high fault-current interruption capability is required.
