What this RCCB does on the line
Depth is 70 mm — the same as the installation depth, so no extra clearance needed behind the rail. Supply can enter from top or bottom. The IP20 rating applies when installed in a distribution board with conductors connected — standard for enclosed panel use.
The 6 kA SCCR (IEC 61008-1 / EN 60898) is the maximum prospective fault current the device can safely interrupt. The 100 mA sensitivity is higher than the typical 30 mA for personal shock protection; it's used where the goal is fire protection or equipment protection on circuits with higher natural leakage. The I²t let-through of 110,000 A²s and peak let-through current of 7,100 A are the energy and current the RCCB allows downstream during a fault — useful for coordinating with downstream MCBs.
