The 73.5 mm depth fits standard distribution boards; tunnel terminals accept up to 35 mm² rigid cable at the bottom, with a tightening torque of 3.5 N.m.
The 30 mA sensitivity is the standard threshold for personal protection against indirect contact — it trips within the IEC 61009-1 time curve before a fault current reaches a dangerous level for a human body. Rated operational voltage is 110...130 V AC, 50/60 Hz — sized for single-phase line-to-neutral supplies in that band. Insulation voltage is rated 500 V AC, impulse withstand 6 kV, pollution degree 3, so it holds up in industrial panels where transient spikes and conductive dust are present. The voltage-independent trip mechanism means the RCD does not need a separate power supply or neutral reference to open on a fault — it uses the fault energy itself, so it remains functional even if the neutral is lost upstream.
This is an outgoer device — it sits on the load side of the iC60 MCB, plugging in via the integrated electrical connection. The clip-on DIN rail mount and 36 mm width (4 modules) mean it takes up four standard 9 mm pitches in a distribution board. Bottom connection accepts comb busbars for daisy-chaining multiple outgoing circuits.
