✅ Replacement Summary
- Main circuit rating fully equivalent: Подходит для 335 кВт, 400 V motor. Keep busbar torque at 58 Н·м; 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.
- Ограничение: Max operating rate reduced to 600 циклов/час. Applications with frequent inching or high cycle count need evaluation.
- Temperature rise & надежность: Giga higher insulation voltage, lower contact loss and wider ambient temperature range, ideal for critical continuous-duty loads.
⚠️ Engineering Replacement Risk Notes
Оригинал 240 V AC control supply can connect directly to LC1G630KUEC coil.
Do not replace directly for heavy inching / frequent reversing >600 циклов/час; performance review mandatory.
Much narrower frame width; existing busbars and protective baffles need rework.
