The trip is instantaneous — no intentional delay — so it clears leakage faults as fast as the internal voltage-dependent sensing circuit allows.
63 A rated current and 300 mA sensitivity are specified.
Panel integration
Clip-on mounting to DIN rail, 4 modules wide (72 mm). The screw connection to the MCB means it physically attaches to the outgoing terminals of the iC65 breaker — no additional wiring between MCB and RCD. The trip indicator gives a local visual signal when the device has tripped on leakage, which helps during fault finding on a crowded rail.
