The RCBOResidual Current Circuit Breaker with Overcurrent Protection is an electrical protection device that combines the functions of an earth leakage protector and a circuit breaker. It has the following product advantages and features: 1. Leakage protection function: RCBO will immediately cut off the leakage circuit to protect personal safety. 2. Overload protection function: RCBO can also detect whether there is an overload current in the circuit, the circuit load is too large, RCBO will automatically cut off the power. 3. Space saving: RCBO DPN integrates the functions of earth leakage protector and circuit breaker in a space of 18mm, saving installation space and cost. 4. High sensitivity: RCBO's leakage protection function can detect very small leakage currents, providing higher safety. 5. Resettable: RCBO can be manually reset after the detection of leakage, which can be more convenient to restore power. 6. Isolation function: RCBO can provide circuit isolation function to facilitate maintenance and replacement of equipment. In short, RCBO has multiple features such as leakage protection, overload protection, high sensitivity, resettable, space saving and isolation function, which is a very practical and safe electrical protection equipment. RCBO (Residual Current Circuit Breaker with Overcurrent Protection) is an electrical protection device that combines a leakage protector and an overload protector in one, and is suitable for the following scenarios. RCBO is suitable for the following scenarios. Household electricity: RCBO can be used for circuit protection in the home, such as protecting appliances in wet environments such as bathrooms and kitchens, as well as other important equipment such as air conditioners and water heaters. Commercial electricity: RCBO can be used for commercial electricity, such as protecting circuits and electrical equipment in retail stores, restaurants, etc. Industrial power: RCBO can be used for industrial power, such as protecting circuits and equipment in factories, workshops and other places. Medical institutions: RCBO can also be used in medical institutions, such as protecting circuits and equipment in places such as operating rooms and treatment rooms for the safety of medical staff and patients. In short, RCBO is suitable for applications where both electrical equipment and personal safety are required. When selecting an RCBO, parameters such as rated current and sensitivity of the electrical protection equipment need to be determined according to the actual use scenario and circuit load.
