- Mounting Plate Hole Dimensions (معيار 3 القطب)
2.1 Mounting Hole Spacing
| مواصفة | LC1F630 | LC1G630KUEN | Retrofit Key Points |
| Horizontal Hole Pitch G (pole-wise spacing) | 90 مم | 70 مم | Old and new holes offset horizontally; original holes cannot be reused |
| Vertical Hole Pitch J (top-bottom spacing) | 220 مم | 242 مم | Vertical spacing increased |

2) Add transition steel plate: Prefabricated adapter plate matching original LC1F hole pitch without cabinet plate modification (recommended for mass retrofits)
Schneider original replacement kit LA9GRT630 – dedicated transition bracket compatible with original LC1F mounting holes.
- Main Circuit Busbar / Terminal Interface Comparison
| غرض | LC1F630 | LC1G630KUEN | On-Site Wiring Difference |
| Inter-Pole Center Distance | 90مم | 70مم | Busbar span reduced by 20mm; original busbars require re-bending / قطع |
| Terminal Opening Width | 60مم | 48مم | Legacy 60mm-wide busbars cannot be inserted directly into new terminals |
| Max Allowable Busbar Size | 60×5mm | 50×20mm | New model supports thicker double-layer busbars with higher current carrying margin |
| Busbar Layers Per Terminal | Single-layer busbar | Double-layer busbar (standard 52×20mm busbar) | New model allows stacked upper and lower busbars |
| Main Circuit Tightening Torque | 58 ن · م | 80 ن · م | Higher torque requirement for new bolts; extended torque wrench needed |
| Cable Lug Compatibility | Single 185mm² cable lug | Single 185mm² ring lug | Interchangeable lug size but different front-rear installation positions |
Busbar Retrofit Recommendations
- Original 60mm-wide busbars matched to LC1F: Cut down to 48–50mm width
- Change span from 90mm to 70mm and shorten inter-pole connecting segments
- Prioritize original standard 52×20mm connection busbars LA9G630BUS (no bending required)
- Control Circuit Wiring Differences
| المعلمة | LC1F630 | LC1G630KUEN | Retrofit Notes |
| Control Terminal Type | Screw compression terminals | Front plug-in tool-free spring terminals | Control cables require no crimp lugs; التوصيل والتشغيل |
| Control Cable Cross-Section | 1~4mm簡 solid / stranded wire | 0.2~2.5mm簡 | Better compatibility for thin signal wires (PLC feedback) |
| Terminal Layout | Side of unit | Lower front face of unit | No side bending required for easier maintenance access |
| استهلاك طاقة الملف | 1500VA pick-up, 80VA holding | Only 11W holding power | Greatly reduced cabinet temperature rise; no extra cooling fan needed |
| Coil Voltage Compatibility | Single fixed AC/DC rating | KU series universal 100~250V AC/DC | No control transformer replacement required, fits most field circuits |
- Matching Thermal Overload Relay Installation
- LC1F630: LR9F7375, side external mounting with transition busbars required
- LC1G630KUEN: LR9G630, direct bottom plug-in mounting, no transition busbars and smaller overall footprint
- Retrofit Tip: Remove existing external thermal relay bracket, mount thermal relay directly under contactor to shorten wiring length
- Retrofit Risks & Construction Precautions
- Mounting Plate: Old and new hole positions are completely misaligned; do not force contactor fastening. Original transition bracket LA9GRT630 is recommended.
- Main Busbars: Pole spacing reduced by 20mm. Forced assembly of legacy busbars causes terminal stress, overheating and ablation – busbars must be remanufactured.
- Rear Clearance: New model is 11mm deeper. Verify minimum 30mm safety clearance if busbars or cable trunking are installed at cabinet rear.
- Torque Standard: Main circuit torque must reach 80N·m; insufficient torque leads to overheating during long-term operation.
- دوائر التحكم: Shorten legacy screw-type control wires and insert directly into spring terminals without re-crimping lugs.
- Maintenance Advantage: G-series contact cartridges are replaceable separately, while damaged F-series contactors require full unit replacement for lower long-term maintenance costs.
