5. 선택 지침 & 교체 솔루션

5.1 Core Selection Rules

부하 유형: AC-1 (resistance furnace, heater) → suitable for LC1F1250MD; AC-3 (모터) → operate with derating or select dedicated AC-3 contactor

Control Supply: 220VDC → choose MD suffix; 220VAC → choose M7 suffix; refer to Schneider coil code table for other voltages

설치공간: Width 309mm, reserve sufficient cabinet space; for compact layout adopt LC1G series (smaller dimension)

보조 연락처: No built-in auxiliary contacts by default; order LAD9 series auxiliary modules separately

Maintenance Convenience: Drawer-type coil structure; coil replacement without disconnecting main circuit wiring, ideal for frequent maintenance scenarios
