Description
About the Product
The AU RCCB 63A FP 415V ADI 30mA is a high-capacity four pole Residual Current Circuit Breaker designed to provide effective protection against earth leakage faults in three phase electrical systems. It safeguards users & installations by rapidly disconnecting power when leakage currents are detected, reducing the risk of electric shock & electrical hazards.
Featuring ADI (Advanced Detection Intelligence) technology, this RCCB ensures precise sensing & consistent operation. With a 63A rating, it is suitable for medium to high load three phase applications in industrial & commercial environments.
How the RCCB Works
This RCCB provides dedicated earth leakage protection through continuous monitoring:
• Monitors current balance across all three phases & neutral
• Detects imbalance caused by leakage current or insulation failure
• Trips instantly when leakage exceeds 30mA threshold
• Disconnects all three phases & neutral simultaneously
This ensures rapid fault isolation & enhances safety in three phase systems.
Electrical Configuration
• Rated current: 63A
• Poles: Four pole (FP – 3 phase + neutral)
• Rated voltage: 415V AC
• Technology: ADI (Advanced Detection / Intelligent sensing)
• Sensitivity: 30mA
• Function: Earth leakage protection only
• Application: Personal safety & leakage fault protection
Construction & Design
