It's rated 63 A continuous (In) with a 100 mA earth-leakage sensitivity, covering the standard Type AC waveform (sinusoidal AC residual currents). The 2-pole (2P) unit clips onto a DIN rail, occupying 36 mm of panel width, and is intended for outgoing feeder protection in distribution boards.
The 63 A rated current (In) sets the continuous load capacity — sized for a main incomer or sub-feed on a 230–240 V AC single-phase circuit. The 100 mA sensitivity is less sensitive than the common 30 mA type; it's chosen where a higher leakage threshold is acceptable (e.g., circuits without socket outlets, or where nuisance tripping from equipment leakage is a concern). The voltage-independent trip mechanism means the RCCB disconnects on earth leakage even if the line voltage is lost — a safety advantage over electronically tripped units. The instantaneous time delay provides no intentional delay; it trips within the standard RCCB response window, so it's not for selectivity with downstream delayed RCCBs unless coordinated by fault current magnitude. The insulation voltage (Ui) is 500 V AC, and the operational voltage (Ue) is 230–240 V AC, 50 Hz only.
Clip-on mounting to DIN rail — standard 35 mm rail. The 36 mm width occupies two 18 mm modular pitches (9 mm pitches: 4, so 36 mm total). Depth is 74.5 mm, height 96 mm. Terminals accept 1–35 mm² rigid or 1–25 mm² flexible wire; tightening torque is 3.5 N·m top or bottom. Wire stripping length is 14 mm. The neutral position is left. IP20 finger protection — suitable for enclosed distribution boards; IP40 with the modular enclosure.
