- Key Selection & Application Tips
- 遮断容量のマッチング: Select frame size based on the system’s maximum short-circuit current. Frame I is suitable for scenarios ≤66kA, while Frame II is for ≤100kA. あ 20% margin is recommended.
- Trip Unit Setting: Enable LSIG protection for motor loads, with the ground fault setting recommended at 0.3–0.5In. LSI protection is sufficient for power distribution loads.
- 通信互換性: Select COM15/COM16 module for remote monitoring, ensuring protocol compatibility with PLC/SCADA systems (PROFIBUS/MODBUS).
- 設置スペース: The drawout type occupies approximately 160mm more depth than the fixed type. Reserve sufficient operation and maintenance space during cabinet design.
- 交換 & アップグレード: The 3WL series has been upgraded to the 3WA series (例えば, 3WA1116-3EG45-4GA4), featuring compatible dimensions and protection functions, plus added Ethernet communication and intelligent diagnosis.
