Why Choose the ABB 1SDA072991R1 E2.2H 1600 Ekip Dip LI 4p WMP Air Circuit Breaker?
The ABB 1SDA072991R1 is a high-performance SACE Emax 2 E2.2H four-pole air circuit breaker moving part designed for protection and switching in demanding low-voltage electrical distribution systems. Rated at 1600 A, this withdrawable breaker combines ABB's high-breaking-capacity E2.2H frame with an Ekip Dip LI electronic protection release.
The Ekip Dip LI release provides long-time (L) overload protection and instantaneous (I) short-circuit protection. The overload release can be adjusted from 640–1600 A, while the instantaneous short-circuit release is adjustable from 2400–24000 A, enabling the breaker to be configured for the protection requirements of the connected distribution circuit.
The E2.2H performance level provides a rated ultimate short-circuit breaking capacity of 100 kA at 400–440 V AC and 85 kA at 500–690 V AC, together with a rated short-time withstand current of 85 kA for 1 s. Its four-pole withdrawable moving-part (WMP) construction supports maintainable switchboard designs where high fault-current performance and operational reliability are required.
