- Installation and Maintenance Notes
- 設置上の注意事項
For fixed mounting, reserve sufficient operating space (handle space ≥120mm)
Tighten terminals to specified torque (recommended for copper conductors: 40N·m for M10 bolts)
Maintain spacing ≥20mm between side-by-side units for proper heat dissipation
- メンテナンスに関する推奨事項
Regular inspection (at least once per year): 外観, fasteners, operating mechanism flexibility
After short-circuit tripping, inspect contact condition and replace if necessary
Thermal-magnetic trip units are non-adjustable; replace with electronic trip models if parameter adjustment is needed
- Selection and Replacement Recommendations
- Selection Factors
System short-circuit current level (ensure Icu ≥ calculated value)
Load type (D-curve for distribution protection, motor-specific type for motor protection)
Installation space and operation method
Future expansion (reserve 10%–20% margin)
- 代替ソリューション
For more precise protection and adjustable parameters, upgrade to CVS630F ETS2.3 electronic trip model
For communication and remote monitoring, select NSX630F series with intelligent trip units such as Micrologic 5.3A
For budget-limited projects, consider domestic alternatives including Chint NM1 and Delixi CDM3 series
