Why Choose the ABB XT5N 400 Ekip Dip LS/I In=400 3p F F?

The XT5N 400 Ekip Dip LS/I In=400 3p F F stands out for its high short-circuit breaking capacity of 70 kA, making it suitable for installations close to transformer secondaries or generator outputs where fault currents can be severe. The Ekip Dip electronic trip unit provides precise LS/I (Long-time and Instantaneous) protection functions, allowing engineers to fine-tune tripping parameters directly on the device without additional programming hardware. Its compact fixed-frame design optimises panel space while maintaining full 400 A rated current capability, and IEC 61850 support future-proofs the installation for smart grid and digital substation integration.
