RCD Type B

Also known as: type-b-rcd, rcd-type-b-vfd, frequentieregelaar-rcd, vfd-aardlekschakelaar, ev-rcd-type-b, dc-lekstroom

Detects smooth DC leakage currents up to 1 kHz+. Required for three-phase inverters (PV panels, EV chargers without galvanic isolation) where Type A does not ensure safety—a DC leakage blocks magnetic operation.
