Sélection & Replacement Guide

6.1 Core Selection Principles

Correspondance actuelle: In ≥ 1.2 × load current; frame current ≥ 1.5 × In
Pouvoir de coupure: 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)
