The instantaneous design (no intentional delay) means it clears ground faults within a cycle, which is what you want for a general-purpose feeder or submain where selectivity with downstream RCBOs isn't required. Rated short-circuit current withstand is 10 kA, with a let-through current of 7 100 A and a permissible I²t of 110 000 A²·s.
Where it fits — panel and environment
Depth is 70 mm. IP20 rated with conductors connected and the distribution board installed. The test button will operate down to that voltage — useful to know if you're commissioning on a weak generator or long feeder.
If your load includes VFDs, UPS systems, or LED drivers that generate pulsed DC or high-frequency leakage, you need a Type A or Type B RCCB instead — this one will not trip on smooth DC or mixed-frequency faults. Mechanical endurance is 10 000 switching cycles typical — that's the life of the mechanism, not the electrical endurance at full load. For frequent switching (e.g., EV charging or welder isolation), budget for replacement earlier than that cycle count suggests.
