Description
About the Product
The AU RCBO 40A FP 415V AC 10kA 300mA C Curve is a four pole protection device that integrates both MCB & RCCB functionalities into a single compact unit. It is engineered for three phase systems requiring dependable protection against overload, short circuit, & earth leakage faults.
With a 40A current rating, this RCBO is suitable for high load three phase circuits such as industrial machinery, heavy equipment, & commercial power distribution systems. The 300mA leakage sensitivity is typically used for fire protection & equipment safety 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 full circuit isolation & enhances system safety during fault conditions.
