Description
About the Product
The AU RCBO 40A DP 240V AC 10kA 30mA C Curve is a compact protection device that integrates the functions of both an MCB & an RCCB into a single unit. It is designed to provide comprehensive protection against overload, short circuit, & earth leakage faults.
With a 40A current rating, this RCBO is suitable for high load applications such as heavy appliances, power circuits, & equipment loads. The 30mA leakage sensitivity provides effective protection against electric shock, making it ideal for residential & commercial safety applications.
How the RCBO Works
This RCBO functions as a combined protection system:
• Detects overload & 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 & neutral through double pole operation
This ensures complete circuit protection & reliable isolation during fault conditions.
