6.1 Core Selection Principles

1. Current matching: In ≥ 1.2 × load current; frame current ≥ 1.5 × In
2. Отключающая способность: Icu ≥ expected short‑circuit current (≥50kA recommended for industry)
3. Защита: LS/I for motors; LS for distribution; LSIG for sensitive loads
4. Монтаж: F = Fixed, D = Plug‑in, W = Drawout (FF = Fixed Front)

6.2 Replacement Steps

1. Confirm frame + breaking class + release + столбы
2. Match equivalent frame from target brand
3. Maintain breaking capacity ≥ original
4. Verify mounting dimensions and connections
