Siemens 3RT2024-1AP00｜Cross-Brand Equivalent Comparison Table

Baseline specification: 3피, AC-3 12A, 5.5kW@400V, AC230V 50Hz coil, built-in 1NO+1NC auxiliary contacts, 나사 터미널, DIN 레일

⚠️ Note: Electrically equivalent replacement; overall dimensions, 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. 보조 연락처: The reference model has built-in 1NO+1NC. Many economical models only have 1NO (예를 들어. LC1N1210), cannot be directly replaced due to missing NC feedback contact. Must select suffix 1211 (1아니요+1NC).
2. 코일 전압: Baseline AC230V 50Hz. Distinguish:

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

3. 장착 치수: 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. 기계적 인터록 & 부속품: Cross-brand accessories not interchangeable. Reversing interlock modules and side-mounted auxiliary contacts cannot be mixed.
