Applications & Use Cases

The E1.2B 1600 Ekip Dip LSI 3p F F air circuit breaker is well suited for main and sub-main incomer protection in low-voltage main distribution boards (MDBs) and power distribution panels. Its high 1600 A rated current and 42 kA breaking capacity at 400 V AC make it ideal for protecting busbars, transformers, generators, and large motor feeders in industrial plants, commercial buildings, data centres, and infrastructure projects. The Ekip Dip LSI trip unit provides adjustable L, S, and I protection thresholds directly via DIP switches, simplifying on-site commissioning without the need for external configuration tools. The fixed (F F) mounting configuration ensures a compact, cost-effective installation in switchgear assemblies where drawout functionality is not required.
