Description
About the Product
The AU RCBO 63A DP 240V AC 10kA 30mA C Curve is a high-capacity protection device that integrates both MCB & RCCB functionalities into a single unit. It is designed to protect electrical circuits from overload, short circuit, & earth leakage faults in high load applications.
With a 63A rating, this RCBO is suitable for heavy-duty circuits such as main power lines, large appliances, & industrial equipment. The 30mA leakage sensitivity provides effective protection against electric shock, making it suitable for safety-critical applications in residential, commercial, & industrial environments.
How the RCBO Works
This RCBO operates as a combined protection system:
• Detects overload & short circuit conditions similar to an MCB
• Detects earth leakage currents similar to an RCCB
• Automatically trips when abnormal conditions are detected
• Disconnects both live & neutral through double pole operation
This ensures complete circuit isolation & comprehensive protection against electrical faults.
Electrical Configuration
• Rated current: 63A
• Poles: Double pole (DP)
• Rated voltage: 240V AC
• Breaking capacity: 10kA
• Sensitivity: 30mA
• Trip curve: C Curve
• Application: Overload, short circuit, & earth leakage protection
