1. What Is an RCBO?
1. What Is an RCBO?
An RCBO (Residual Current Circuit Breaker with Overcurrent Protection) combines leakage, overload, and short-circuit protection in a single device, ensuring maximum safety for electrical circuits.
All-in-One Circuit Protection
Leakage + Overload + Short-Circuit – One Device Does It All
Unlike RCCBs that only detect earth leakage, RCBOs combine the functions of both an RCCB and an MCB. This means they not only cut off power when leakage occurs, but also protect against overloads and short circuits that could damage wiring or appliances.
With this all-in-one protection, RCBOs are widely used in residential apartments, office buildings, and industrial facilities. They are particularly suited for critical circuits such as air conditioners, water heaters, and EV charging points, where independent and reliable safety is essential.
By installing RCBOs, users gain improved selectivity—faults are isolated to the affected circuit only, preventing unnecessary power outages across the whole system. This ensures higher safety, better convenience, and reduced downtime..
2. Selectable Leakage Protection Function
2. Selectable Leakage Protection Function
Soltree breakers feature a convenient switch that lets users turn leakage protection on or off, making the device adaptable to different environments and needs.
Two Modes, One Device
With the selectable leakage function, users can easily choose how the breaker operates:
Leakage ON
With the selectable leakage function, users can easily choose how the breaker operates:
Leakage OFF
Functions as a standard MCB, avoiding nuisance trips in environments prone to humidity or temporary leakage.
This dual-mode design provides greater flexibility, allowing one device to serve both as a leakage protector and as a regular breaker, depending on the application scenario.
3. Visual Status Indicator Window
3. Visual Status Indicator Window
Actuair RCCBs and RCBOs are equipped with a clear indicator window that shows the real-time status of the device at a glance.
Instant Status Recognition
The built-in indicator window provides a quick and reliable way to check the working status of the breaker. When the window shows green, it means the device is ON and the circuit is operating normally; when it shows red, it indicates that the breaker is OFF and the circuit has been disconnected.
This clear visual feedback helps users and electricians instantly understand the status of the system without the need for extra tools or testing. By simplifying daily checks and troubleshooting, the indicator window not only saves time but also enhances overall safety and confidence in operation. Whether in residential, commercial, or industrial environments, it ensures that circuit protection is always visible and easy to manage.
