Residual Current Circuit Breakers (RCCBs) are widely used in various application scenarios to ensure safety and protection against electrical leakage currents and electric shocks caused by indirect contacts. Some common application scenarios include:
Residential buildings: RCCBs are used in homes to protect electrical circuits and appliances from earth leakage currents, ensuring the safety of occupants.
Commercial buildings: In offices, shops, and other commercial spaces, RCCBs help protect employees and customers from potential electric shock hazards due to leakage currents.
Industrial facilities: Factories and other industrial settings often involve the use of heavy machinery and equipment, which can pose a higher risk of electrical faults. RCCBs are employed to provide protection against such risks.
Outdoor installations: In outdoor electrical installations, such as lighting systems, garden equipment, or swimming pool installations, RCCBs are crucial to protect against electric shocks caused by moisture or other environmental factors.
Combined protection with RCBOs: Residual Current Circuit Breakers with Overcurrent Protection (RCBOs) are used when there is a need to combine protection against overcurrent (overload and short-circuit) and protection against earth leakage currents.
| 1. What is the Residual Current Circuit Breakers (RCCB)? 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. | |

| 2. What is the function of RCCB? | |
| The function of RCCB is to cut off the circuit when the current leaks to protect personal safety and electrical equipment. RCCB is a kind of residual current protector, which can detect any leakage current in the circuit and cut off the circuit quickly when the leakage is detected. This device is commonly used in homes and commercial buildings to ensure the safety of electrical circuits. | |
| 3. What is the difference between RCCB and MCB? | |
| RCCB and MCB are two different types of circuit protectors. MCB (miniature circuit breaker) is a device used to protect electric circuits, which can automatically cut off the current when the circuit is interrupted by current overload or short circuit. The RCCB (Residual Current Circuit Breaker) is a protector used to detect and cut off the grounding current. When the grounding current exceeds the set value, the RCCB will automatically cut off the current to protect personal safety. In general, RCCB needs to be used together with MCB to protect the circuit from short-circuit current and overload current and leakage current. | |
| 4. How to test the working status of RCCB? | |
| The working status of RCCB (residual current operated protector) can be tested by the test button. The test button simulates a leakage current and if the RCCB is working properly it should trip within seconds. Please make sure that all electrical equipment is turned off before testing, and reset the test button immediately after the test is completed. Consult a professional electrician if you are unsure how to perform the test. |
