✅ Key Notes for Cross-brand Replacement (Engineering)
- 補助接点: The reference model has built-in 1NO+1NC. Many economical models only have 1NO (例えば. LC1N1210), cannot be directly replaced due to missing NC feedback contact. Must select suffix 1211 (1NO+1NC).
- コイル電圧: Baseline AC230V 50Hz. Distinguish:
M7=AC220V 50/60Hz; P7=AC230V 50Hz (fully matches coil of this model)
- 取付寸法: 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.
- 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.
- 機械的インターロック & 付属品: Cross-brand accessories not interchangeable. Reversing interlock modules and side-mounted auxiliary contacts cannot be mixed.
