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
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
Works as a full RCCB/RCBO with earth leakage protection for maximum safety.
- 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
Soltree 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.
4. RCCB vs RCBO: Find the Right Protection for Your Needs
RCCB or RCBO? Find the right protection for your power system, from essential leakage safety to advanced all-in-one coverage.
| Item | RCCB | RCBO | ⭐ Recommendation |
|---|---|---|---|
| Definition | Residual Current Circuit Breaker — leakage (earth fault) protection only. | Residual Current Breaker with Overcurrent — leakage + overload + short-circuit. | Choose RCCB as main leakage protection with separate MCBs; choose RCBO for one-device full protection on each circuit. |
| Main Function | Leakage protection | Leakage + overload + short-circuit | RCBO = RCCB + MCB (all-in-one) |
| Overload / Short-circuit | Not included — requires separate MCB | Built-in overcurrent protection | RCBO simplifies wiring and saves panel space |
| Leakage Sensitivity | Common trip values: 30 mA (personal safety), 100/300 mA (fire prevention), depending on model | Both support similar IΔn options | |
| Typical Poles | 2P / 4P (often for main protection) | 1P+N / 2P / 3P / 4P (per-circuit protection) | 1P+N RCBOs are popular for single-phase branch circuits |
| Applications |
|
|
|
| Pros |
|
|
|
| Considerations | Needs extra MCBs for overload & short-circuit; more wiring | Unit price higher than MCB; usually one per branch | Balance safety, space, and budget |
| Certification | IEC 61008-1 / 61009-1, CE, RoHS (model-dependent) | Select ratings: In, Ics, IΔn, curve (e.g., B/C) | |
| Price Positioning | Lower (with separate MCBs overall) | Higher per device but best value for per-circuit safety | RCBO often recommended for key circuits |
5. Flame-Retardant Safety in Every Breaker
Our RCBOs and RCCBs are built with high-quality flame-retardant materials that resist ignition and slow fire spread, ensuring reliable protection even in extreme conditions.
Durable, Heat-Resistant Design
Our RCBOs and RCCBs use flame-retardant housings that resist heat and ignition, significantly reducing the risk of electrical fires caused by overload, short-circuit, or faulty wiring. The materials are self-extinguishing and maintain durability even under prolonged high-temperature operation, ensuring long-term safety and reliability.
In addition to superior fire resistance, every unit is tested to meet stringent international standards such as IEC, CE, and RoHS, giving customers confidence in both quality and compliance. This flame-retardant design makes our breakers especially valuable in environments where safety cannot be compromised, including residential apartments, office buildings, hotels, factories, and critical infrastructure.
6. Wide Temperature Range: Reliable in Heat and Cold
Our RCBOs and RCCBs are engineered to operate safely under extreme temperatures, ensuring consistent performance from freezing winters to scorching summers.
Built to Withstand Harsh Environments
Thanks to advanced flame-retardant and heat-resistant materials, Soltree breakers maintain durability and safety even in challenging environments. Whether exposed to low temperatures that can cause brittleness or high heat that stresses components, our devices remain reliable and compliant with international safety standards.
- Operates reliably from -25°C to +55°C
- Resistant to humidity and sudden temperature changes
- Suitable for outdoor panels, factories, and extreme climates
- Ensures reliable protection for homes and industries
7. Monthly Test for Reliable Safety
All RCCBs and RCBOs are equipped with a built-in test button to ensure the device works properly and provides continuous protection.
Easy Testing, Maximum Assurance
By pressing the test button, users can simulate a leakage fault and confirm that the breaker trips correctly. This simple monthly check ensures the internal mechanism is functioning, preventing hidden failures and guaranteeing safety when real leakage occurs.
- Quick and easy self-test in seconds
- Ensures leakage protection works reliably
- Recommended monthly for all installations
- Essential for households, offices, and industrial sites
