Description
About the Product
The AU RCBO 63A FP 415V AC 10kA 100mA C Curve is a high capacity four pole protection device that integrates both MCB & RCCB functions into a single compact unit. It provides reliable protection against overload, short circuit, & earth leakage faults in demanding three phase systems.
With a 63A current rating, this RCBO is suitable for heavy duty applications such as main distribution lines, industrial machinery, & commercial power systems. The 100mA leakage sensitivity is typically used for equipment protection & fire safety in installations where higher leakage thresholds are required.
How the RCBO Works
This four pole RCBO functions as a complete 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 all three phases & neutral simultaneously
This ensures complete circuit isolation & enhances safety in three phase electrical systems.
