FAQ
| 1. What are the types of RCBO? RCCB is a kind of leakage protector, which is called residual current operated circuit breaker. It can detect the leakage current in the circuit, and when the leakage current exceeds the set value, the RCCB will automatically cut off the circuit to protect personal safety. | |
| Here are a few common RCBO types: 2 pole RCBO: suitable for single phase circuits. 4-pole RCBO: suitable for three-phase circuits, which can provide better leakage protection. Type A RCBO: Suitable for environments that are dangerous to the human body, such as residential areas, hospitals, etc. AC type RCBO: suitable for environments with non-pure resistive loads, such as lighting, household appliances, etc. Type F RCBO: Suitable for environments where there is a risk of arc faults, such as industrial equipment, etc. | |
| 2. What is the working principle of RCBO? | |
| RCBO is a combined circuit breaker with leakage protection and overload/short circuit protection. The working principle of RCBO is that when any leakage is detected in the circuit, it will cut off the circuit immediately to protect people from the danger of electric shock. In addition, if there is an overload or short circuit in the circuit, RCBO will also cut off the circuit immediately to prevent dangers such as fire. Therefore, RCBO is a very important electrical equipment that can protect people's lives and property safety. | |
| 3. What is the difference between RCBO and RCD? | |
| Both RCBO and RCD are devices used for circuit protection, but they do different things. The full name of RCD is residual current action protector. It is mainly used to detect whether there is leakage in the circuit. Once leakage is found, it will quickly cut off the circuit to protect personal safety. RCBO is called residual current circuit breaker with overload protection. It can not only detect leakage, but also detect overload and short circuit, and cut off the circuit when these problems are detected to protect the safety of electrical equipment. Therefore, RCBO has more comprehensive protection functions than RCD. | |
| 4. How to choose the rated current and rated leakage action time of RCBO? | |
| Circuit rated current: The rated current of the RCBO should match the rated current of the circuit to ensure quick disconnection of the power supply in the event of a circuit overload or short circuit. Type and quantity of electrical equipment: Different types and quantities of electrical equipment have different loads on the circuit, so it is necessary to select the appropriate RCBO rated current according to the actual situation. Leakage protection requirements: Select the rated leakage action time of RCBO according to the leakage protection requirements. It is usually recommended to choose the rated leakage action time of 100 ms or 300 ms. | |
| 5. Under what circumstances should RCBO be used? | |
| RCBO (Residual Current Circuit Breaker with Overcurrent Protection) is an electrical protection device that can automatically cut off the circuit when the current is overloaded or leaked. Therefore, RCBOs are often used in situations where additional safety protection is required, such as using electrical equipment in wet environments, using electrical appliances with grounding, or in places where people need to be protected. Additionally, RCBOs are commonly used in residential, commercial and industrial facilities to ensure the safety and reliability of electrical systems. |
