Applications & Use Cases

The ABB E1.2N 1000 Ekip Dip LI 4p F F air circuit breaker is widely specified for main incoming and bus-coupler positions in low-voltage main distribution boards (MDB), power distribution centers (PDC), and motor control centers (MCC). Its 1000 A rated current and 66 kA breaking capacity at 400 V AC make it suitable for protecting downstream feeders, large motors, transformers, and generators in industrial plants, data centers, infrastructure projects, and commercial buildings. The four-pole fixed configuration supports both three-phase plus neutral (3P+N) installations, ensuring comprehensive circuit protection across all live and neutral conductors.
