Engineering Analysis
The 30mA sensitivity level is specifically chosen for residential safety because it triggers a trip before leakage current causes permanent physiological harm to humans. With a 10kA conditional short circuit rating, this device maintains structural integrity when paired with a backup MCB during severe fault events. The 2-pole configuration is vital for residential final circuits as it provides simultaneous isolation of both the phase and neutral lines during a fault.
