Engineering Analysis
The 100mA sensitivity is engineered for fire protection, as it interrupts the circuit within 300ms before leakage currents can generate sufficient heat to ignite building materials. Featuring a 10kA breaking capacity and a 400A making/breaking capacity, this unit ensures robust performance during high-fault conditions at the main distribution point. The 4P configuration incorporates a switched neutral, ensuring that the neutral line is disconnected simultaneously with the phases for complete fault clearance.
