Description
About the Product
The AU RCBO 20A DP 240V AC 10kA 30mA C Curve is a compact protection device that integrates the functions of an MCB and an RCCB into a single unit. It provides protection against overload, short circuit, and earth leakage faults in electrical circuits.
With a 20A current rating, this RCBO is suitable for medium load applications such as socket circuits, appliances, and equipment loads. The 30mA sensitivity offers effective protection against electric shock, making it ideal for residential and commercial safety applications.
How the RCBO Works
This RCBO operates as a combined protection system:
- Detects overload and short circuit conditions similar to an MCB
- Detects earth leakage currents similar to an RCCB
- Trips automatically when abnormal conditions are detected
- Disconnects both live and neutral through double pole operation
This ensures complete circuit protection and safe isolation during fault conditions.
Electrical Configuration
- Rated current: 20A
- Poles: Double pole (DP)
- Rated voltage: 240V AC
- Breaking capacity: 10kA
- Sensitivity: 30mA
- Trip curve: C Curve
- Application: Overload, short circuit, and earth leakage protection
Construction and Design
The RCBO is designed for reliable performance and compact installation:
- Integrated MCB and RCCB functionality in one device
- Modular design compatible with DIN rail mounting
- Compact construction for efficient panel space usage
- High mechanical and electrical endurance
- Designed for consistent and accurate tripping performance
Safety and Protection
- Protects against overload and short circuit faults
- 30mA sensitivity provides protection against indirect electric shock
- Detects and isolates earth leakage currents
- Double pole isolation ensures complete disconnection of the circuit
- Reduces risk of electrical hazards and equipment damage
Mounting and Durability
- DIN rail mounting for easy installation in distribution boards
- Compact modular construction
- Suitable for frequent operation and fault conditions
- Built for long term durability and stable performance
Application Domains
- Residential electrical distribution systems
- Commercial installations
- Socket circuits and appliances
- General purpose electrical protection
- Distribution boards requiring combined protection
Key Features
- 20A rated RCBO for medium load circuits
- Double pole design for complete circuit isolation
- 10kA breaking capacity for reliable fault interruption
- 30mA sensitivity for general electrical safety
- C curve characteristic for standard applications
- Combines MCB and RCCB functions in one device
- DIN rail compatible for easy installation
Applications
- Residential distribution boards
- Commercial electrical systems
- Socket outlets
- Appliance circuits
- General protection installations
FAQs
1. What is an RCBO?
Ans: An RCBO is a device that combines the functions of an MCB and an RCCB, providing protection against overload, short circuit, and earth leakage.
2. What does 30mA sensitivity mean?
Ans: It indicates the leakage current level at which the device trips and is commonly used for protection against electric shock in general applications.
3. What is the advantage of a double pole RCBO?
Ans: It disconnects both live and neutral, ensuring complete isolation of the circuit during faults.
4. What does 10kA breaking capacity indicate?
Ans: It represents the maximum fault current the device can safely interrupt.
5. What is a C curve characteristic?
Ans: It is suitable for general purpose circuits with moderate inrush currents such as appliances and socket loads.
6. Where can this RCBO be used?
Ans: It is used in residential and commercial installations requiring combined electrical protection.
