Baseline specification: 3P, AC-3 12A, 5.5kW@400V, AC230V 50Hz coil, built-in 1NO+1NC auxiliary contacts, terminali a vite, Guida DIN

⚠️ Nota: Electrically equivalent replacement; dimensioni complessive, cutouts and accessories may not be fully compatible. Verify mounting dimensions and auxiliary contact configuration before cabinet retrofit.

✅ Key Notes for Cross-brand Replacement (Engineering)

1. Contatti ausiliari: The reference model has built-in 1NO+1NC. Many economical models only have 1NO (per esempio. LC1N1210), cannot be directly replaced due to missing NC feedback contact. Must select suffix 1211 (1NA+1NC).
2. Tensione della bobina: Baseline AC230V 50Hz. Distinguish:

M7=AC220V 50/60Hz; P7=AC230V 50Hz (fully matches coil of this model)

3. Dimensioni di montaggio: Siemens S0 frame width 45mm; Schneider LC1D12, ABB AF12 also 45mm width, directly mountable on DIN rail, cutout generally compatible. Depth differs; verify depth if cabinet space is limited.
4. Matched Thermal Relay: Thermal relay model must be changed when switching brand. Contactors and thermal relays from different brands cannot snap-fit together, separate mounting required.
5. Interblocco meccanico & Accessori: Cross-brand accessories not interchangeable. Reversing interlock modules and side-mounted auxiliary contacts cannot be mixed.
