RCD / Differential Protection
Residual current protection devices for fault protection, personal safety and electrical installation protection.
Technical description
RCD / differential protection devices detect residual current faults and disconnect the circuit when the leakage threshold is exceeded.
They are selected according to sensitivity, type, pole count, current rating and installation requirements.
Typical use cases
- Personal protection at 30 mA
- Fire or installation protection at higher sensitivity levels
- Residential electrical boards
- Commercial distribution boards
- Wet-room and technical circuit protection
