RCBO: Core Barrier for Earth Leakage Protection in Power Systems

With electricity widely applied in civil, industrial and commercial scenarios, the risks of electric shocks and equipment damage caused by earth leakage have become increasingly prominent. As an integrated device with overload protection, short-circuit protection and earth leakage protection, the Residual Current Breaker with Overcurrent protection (RCBO) is a key element for protecting personal and equipment safety.

Different from RCCB, RCBO integrates dual functions of overload & short-circuit protection and earth leakage protection.When abnormalities such as earth leakage or personal electric shock occur in the circuit, leading to the residual current exceeding the preset threshold,RCBO will quickly cut off the power supply in milliseconds, minimizing the risks of casualties and property losses.

Application Scenarios:

● Household area: Effectively prevents electric shocks caused by household appliance leakage and line aging in residences, apartments and other scenarios, safeguarding household electricity safety.

● Industrial workshops: Addresses earth leakage hazards during equipment operation in machining, chemical, textile and other industries, protecting the personal safety of operators and avoiding production interruptions due to equipment damage from earth leakage.

● Public service places: Widespread application in densely populated areas such as schools, hospitals and subways provides a safe electricity environment for public travel and activities.
