- Auswahl & Replacement Guide
6.1 Core Selection Principles
- Aktuelle Übereinstimmung: In ≥ 1.2 × load current; frame current ≥ 1.5 × In
- Bruchkapazität: Icu ≥ expected short‑circuit current (≥50kA recommended for industry)
- Protection: LS/I for motors; LS for distribution; LSIG for sensitive loads
- Montage: F = Fixed, D = Plug‑in, W = Drawout (FF = Fixed Front)
6.2 Replacement Steps
- Confirm frame + breaking class + release + Stangen
- Match equivalent frame from target brand
- Maintain breaking capacity ≥ original
- Verify mounting dimensions and connections
