✅ Replacement Summary

Main circuit rating fully equivalent: 적합 335 kW, 400 V motor. Keep busbar torque at 58 N·m; Mounting hole layout differs, base plate re-drilling required.
Control circuit advantage: LC1G630KUEC wide-range 100~250 V AC/DC coil works directly with original 240 VAC control supply; lower coil power and built-in 1NO+1NC auxiliary contacts, no auxiliary accessory purchase.
한정: Max operating rate reduced to 600 주기/시간. Applications with frequent inching or high cycle count need evaluation.
Temperature rise & 신뢰할 수 있음: Giga higher insulation voltage, lower contact loss and wider ambient temperature range, ideal for critical continuous-duty loads.

⚠️ Engineering Replacement Risk Notes

원래의 240 V AC control supply can connect directly to LC1G630KUEC coil.

Do not replace directly for heavy inching / frequent reversing >600 주기/시간; performance review mandatory.

Much narrower frame width; existing busbars and protective baffles need rework.
