- 설치 및 유지 관리 참고 사항
- 설치시 주의사항
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
- 유지 관리 권장 사항
정기점검 (at least once per year): 모습, 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
- 선택 및 교체 권장 사항
- Selection Factors
System short-circuit current level (ensure Icu ≥ calculated value)
부하 유형 (D-curve for distribution protection, motor-specific type for motor protection)
Installation space and operation method
Future expansion (reserve 10%–20% margin)
- 대체 솔루션
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

- Connection Precautions and Specifications
- 설치 전 준비
Ensure breaker is OFF, disconnect upstream power and verify voltage absence
Clean terminal surfaces and remove oxidation before connection
Select properly sized conductors to avoid overheating or improper fitting
- 배선 표준
Maintain equal length for each phase in main circuit to avoid unbalanced stress
Route control circuit separately from main circuit to reduce electromagnetic interference
Check terminal tightness after wiring to prevent loose connections
Ensure no tools or debris inside the breaker after wiring; reinstall protective covers
