RCBOs (Residual Current Breaker with Overcurrent Protection) are specialised safety devices designed to detect electrical hazards, thus protecting individuals and electrical appliances. These circuit protection devices combine the functions of two essential components: MCB (Miniature Circuit Breaker), which protects against overloads and short circuits, and RCD (Residual Current Device), which protects against earth leakage currents. Essentially, an RCBO provides dual protection in a single unit, safeguarding your electrical system from various potential hazards. Protect your valuable property and appliances with our range of Type B and Type C RCBOs from leading brands, including Eaton, Schneider Electric, ABB, and Legrand, for your domestic and commercial settings.
Why Use an RCBO? Which Type of Protection It Offers?
Incorporating domestic RCBOs into your electrical system can significantly reduce electrical accidents and property damage. RCBOs can enhance electrical safety in both residential and commercial settings. They offer comprehensive protection against:
- Electric Shocks: By rapidly detecting and interrupting earth leakage currents.
- Fires: By preventing overloads and short circuits that can cause electrical fires.
- Equipment Damage: By protecting electrical appliances and devices from damage due to overcurrent conditions.
Benefits of Using an RCBO
Installing RCBOs in various facilities offers unparalleled benefits, such as:
- Enhanced Safety: Provides comprehensive protection against numerous electrical faults.
- Space-Saving: Combines the functions of an MCB and RCD in a single unit.
- Cost-Effective: An economical choice than installing separate MCBs and RCDs.
- Ease of Installation: Typically, an RCBO is easier to install.
Classification of RCBOs Based on Overcurrent Characteristics
The primary classification of RCBOs is based on their overcurrent characteristics, which determine how they respond to different levels of current.
- Class A RCBO: Designed for low-level overcurrents, typically used in residential and commercial applications.
- Class B: Suitable for medium-level overcurrents, often used in commercial and light industrial settings.
- Class C: Intended for high-level overcurrents, primarily used in industrial environments.
Typical Uses of RCBOs
RCBOs are widely used in various applications, including:
- Residential Properties: Protecting outlets, lighting circuits, and appliances.
- Commercial Buildings: Safeguarding electrical systems in offices, shops, and other commercial spaces.
- Industrial Facilities: Protecting equipment and machinery in industrial environments.
- Outdoor Installations: Protecting outdoor power supplies and equipment.
