Troubleshooting of Common Faults
| Fault Phenomenon | Cause Analysis | Troubleshooting Method |
|---|---|---|
| Cannot Close | Short circuit or leakage at the load end | Check the load status |
| Malfunction of the operating mechanism | Replace the product | |
| Mismatch between the circuit breaker's rated current and the load current | Replace with a product of appropriate specification | |
| Check if the residual current accessory has been reset | Press the reset button | |
| High Temperature | Loose terminal screws or uncompressed wires | Tighten the terminal screws |
| Selected wire cross-sectional area is too small | Replace with a wire of appropriate specification | |
| Mismatch between the circuit breaker's rated current and the load current | Replace with a product of appropriate specification | |
| Natural aging of the product, deformation, rust or looseness of components | Replace with a new product | |
| Fails to Trip During Short Circuit | Malfunction of the product's contact system | Replace with a new product |
| Mismatch between the selected circuit breaker and the load's working conditions | Replace with a product of appropriate specification | |
| Too short stripped length of the wire | Re-strip the wire | |
| Wire not inserted into the terminal block | Re-strip the wire and insert correctly | |
| Possible internal mechanism failure of the product | Replace the product |
