Infrastructure: Small substations, data centers, PV systems
Others: OEM equipment, agricultural machinery, marine systems
6.2 Selection Guide
| Requirement | Recommended | Not Recommended |

6.3 Selection Cautions
- Ensure rated current In matches load
- Breaking capacity must meet system short-circuit current (N: 36kA @ 415V)
- Mounting (fixed/plug-in) and connection (front/rear) must match panel design
- Auxiliaries, shunt/undervoltage trips ordered separately
- Not for DC short-circuit protection (use DC-rated model)
