Motor protection circuit breaker for load feeders
The 13 x I_in setting at 160 A L handles short-circuit conditions, while the 690 V rating suits 400 V and 690 V three-phase networks common in European industrial panels.
The 80–160 A adjustable range covers motor FLA from a 30 kW 4-pole induction motor up to roughly 75 kW at 400 V, depending on service factor. The Class 30 electronic trigger means the trip curve allows a longer starting transient — suitable for high-inertia loads like fans, centrifuges, or conveyors that need 20–30 seconds to reach speed. The 13 x I_in short-circuit release at 160 A L (2080 A instantaneous) clears hard faults before upstream devices see them.
