Description
About the Product
The AU RCCB 100A FP 415V ADI 300mA (AURAD410030) is a high-capacity four pole Residual Current Circuit Breaker engineered to detect earth leakage currents in three phase electrical systems. It is primarily designed for applications where fire protection & equipment safety are critical, rather than direct personal protection.
Integrated with ADI (Advanced Detection Intelligence) technology, this RCCB ensures accurate leakage sensing & dependable tripping performance. With a 100A current rating, it is ideal for high load circuits such as industrial distribution systems, commercial power installations, & main electrical panels.
How the RCCB Works
This RCCB provides dedicated leakage protection through continuous monitoring:
• Monitors current balance across all three phases & neutral
• Detects leakage currents caused by insulation faults or system failures
• Trips automatically when leakage exceeds 300mA threshold
• Disconnects all three phases & neutral simultaneously
This ensures rapid isolation of faults & significantly reduces the risk of electrical fires.
