Applications & Use Cases

The E1.2C 1000 Ekip Dip LI 4p F F air circuit breaker is engineered for high-demand low-voltage power distribution applications. Its 1000 A rated current and 50 kA breaking capacity make it well-suited for main incomer and bus-coupler positions in industrial switchgear panels, commercial buildings, data centres, and infrastructure projects. The four-pole fixed configuration ensures protection across all live and neutral conductors, while the Ekip Dip LI trip unit provides configurable long-time and instantaneous protection functions. The ATEX rating further extends its suitability to hazardous-area installations where certified switchgear is mandatory.
