Residual Current Circuit Breakers (RCCBs) are electrical devices designed to prevent electric shock and electrical fires by detecting imbalances in electrical currents. They work by monitoring the flow of electricity through live and neutral wires and will disconnect the circuit if an imbalance is detected, indicating a potential fault. RCCBs are typically made from durable insulating materials and contain sensitive electronic components to ensure rapid response times.
| Rated current | 16A to 125A |
| Rated residual current | 30mA, 100mA, 300mA |
| Number of poles | 2, 3, or 4 poles |
| Operating voltage | 230V to 400V AC |
| Tripping time | 30 milliseconds or less |
| Standards compliance | IEC 61008 |
When selecting a Residual Current Circuit Breaker, consider the rated current and residual current values suitable for your application. It's important to specify the number of poles required based on the circuit configuration. Additionally, ensure compliance with relevant standards and consider the tripping time necessary for your safety needs. Requesting a quote should include the quantity needed and any specific installation requirements.
