AC RCBOs are essential for ensuring the safety of electrical systems. They minimize the risk of electrical fires, damage to equipment, and injuries caused by electric shock. By providing dual protection against overcurrent and residual current faults, they are an indispensable part of any modern electrical installation.
An AC residual current breaker with overcurrent protection (RCBO) is a combined device that protects electrical circuits from both overcurrents and residual currents. It operates by detecting faults and quickly disconnecting the circuit to prevent damage, fire, and injury.
The 125-amp rating of the RCBO makes it suitable for high-power applications. It is commonly used in commercial, industrial, and large residential installations where higher current ratings are necessary. Typical applications include:
Heavy machinery and equipment
Large-scale HVAC systems
Commercial kitchens
Data centers
Electric vehicle charging stations
Enhanced Safety: The combination of residual current and overcurrent protection makes the AC RCBO Breaker highly effective in preventing accidents.
Accurate Detection: Its sensitivity ensures that even minor faults are detected, minimizing the risk of fires or shocks.
Flexibility: Adjustable settings allow customization based on specific electrical setups.
Space Efficiency: Its compact size optimizes space utilization in distribution boards.
Reduced Downtime: Swift tripping action minimizes downtime during faults.
Avoid misoperation, the location is clear at a glance.
Protection is used for infrequent connections, disconnections, and conversions of lines to protect your safety.

A1: It is highly recommended to consult a licensed electrician for the installation of any electrical protection device, including an RCBO 125A. They will ensure proper installation and compliance with local codes and regulations.
A2: Yes, you can use a 125A RCBO for a lower-rated application, provided it meets the application’s requirements. However, it might not be the most cost-effective option, and a lower-rated RCBO might be more suitable.
A3: Routine maintenance should be performed at least once a year, or more frequently if specified by the manufacturer or local regulations. Regular checks ensure the device’s optimal performance and safety.
A4: No, AC RCBOs and MCBs are not the same. While both provide protection against overcurrents, AC RCBOs also protect against residual currents, offering dual protection for electrical installations.
A5: No, AC RCBOs are designed specifically for use with AC power sources. For DC power sources, you’ll need a DC-specific RCBO or protection.
A6: The RCBO might trip due to faulty appliances, wiring issues, or excessive electrical loads.
