Engineering Analysis
The 100mA sensitivity is the industry standard for fire protection, as it detects leakage currents that are too low to trip an MCB but high enough to cause thermal ignition. With a 10kA breaking capacity and a Class 3 energy limiting designation, this device manages high-energy fault conditions far better than standard residential components. The 4P configuration with solid neutral protection ensures that all three phases and the neutral are isolated simultaneously during a fault, preventing dangerous neutral-to-earth potential differences.
