4.2 Critical Selection Rules
- Coil voltage must match: AC coils use M/A/F/Q; DC coils use B/F to avoid burnout.
- Auxiliary contacts as needed: S00/S0 have integrated contacts; S1 and above require 3RH series add-on blocks.
- 授業の休憩時間: Standard duty = S class (≤150kA@400V); 頑丈な / high short-circuit = K/H class.
- アクセサリの拡張: シャントトリップをサポート, 不足電圧トリップ, surge suppressors; accessories compatible with 3RT5/6 series.
- List Usage Instructions
- This list covers general industrial models. For special applications (防爆, high protection), refer to Siemens’ official full catalog.
- 交換時, strictly match poles, 現在, coil voltage and auxiliary contacts to ensure mounting and system compatibility.
- For 4-pole versions, higher breaking class or special accessories, provide additional requirements for refined model selection.
