Engineering Analysis
The 300mA sensitivity level is specifically calibrated for fire protection, as it detects leakage currents that could cause ignition before standard breakers react. With a 6kA breaking capacity and a 4kV impulse withstand voltage, this device maintains structural integrity during high-energy electrical events. The 4P (4P) design with switched neutral is critical in India to prevent potential neutral-to-earth voltage hazards during faults.
