- Seleção & Diretrizes de Operação
- Selection Rules
| Fator | Correct Selection | Risk of Wrong Selection |
| Função | Isolation only; must be used with a circuit breaker | No protection, equipment burnout |
| Poloneses | 3P for IT systems; 4P for TN‑S / TT | Risk of electric shock without neutral isolation |
| Atual | Total load ≤ 504A (80% duty) | Superaquecimento, reduced life |
| Curto-circuito | System Isc ≤ 11.5kA/3s | Soldagem por contato, failure to open |
- Regras de segurança
- 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
- Acessórios: contatos auxiliares, operação motorizada, padlock attachment available
- Key Difference from Circuit Breaker
| Item | Compact INS630 3P | Compact NSX630N 3P |
| Tipo | Load break isolator | Disjuntor em caixa moldada (MCCB) |
| Função | Isolation only | Sobrecarga + proteção contra curto-circuito |
| Capacidade de ruptura | Nenhum, withstand only | Icu = 50kA @ 415V |
| Usage | Manual isolation for maintenance | Automatic protection during operation |
| Conexão | 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.
