- اختيار & Operation Guidelines
- Selection Rules
| Factor | Correct Selection | Risk of Wrong Selection |
| وظيفة | Isolation only; must be used with a circuit breaker | No protection, equipment burnout |
| البولنديين | 3P for IT systems; 4P for TN‑S / TT | Risk of electric shock without neutral isolation |
| حاضِر | Total load ≤ 504A (80% duty) | Overheating, reduced life |
| Short-circuit | System Isc ≤ 11.5kA/3s | Contact welding, failure to open |
- Safety Rules
- Do NOT break under load — operate only at no-load or light load
- Use interlocks with upstream breakers
- Indoor dry environment (-25°C ~ +70°C); outdoor needs IP55 enclosure
- Accessories: اتصالات مساعدة, motor operation, padlock attachment available
- Key Difference from Circuit Breaker
| غرض | Compact INS630 3P | Compact NSX630N 3P |
| يكتب | Load break isolator | Molded case circuit breaker (مكب) |
| وظيفة | Isolation only | الزائد + حماية ماس كهربائى |

| Usage | Manual isolation for maintenance | Automatic protection during operation |
| Connection | Installed after breaker | Main protection device |
Schneider Compact INS630-3P (order code 31114) is a dedicated isolation device for safe maintenance in LV distribution systems.
It must be used with a circuit breaker.
If you require both protection and isolation, use NSX630N.
For economic alternatives, consider LS IS630N or Changshu CM1G.
