The 5SV3412-6: The 100 mA trip and Type A residual current detection mean this RCCB is suited for circuits with pulsed DC fault currents from single-phase rectified loads — common in washing machines, LED drivers, and IT equipment. It is not a G-type (short-time delayed) device; the switching function is instantaneous with no intentional delay, so it trips immediately on fault. The 25 A rating holds across the full 40 °C to 60 °C ambient range without derating (–); at 65 °C it derates to 23.3 A, and at 70 °C to 17.6 A (–). For a panel that sees sustained high ambient temperatures, the 25 A nominal gives roughly 2 A of headroom before derating starts at 65 °C. The let-through current is limited to 5 200 A, and the permissible I²t is 58 000 A²·s, which helps with downstream coordination.
Depth is 70 mm, height 90 mm. Installation depth matches the depth dimension. IP20 rating applies once the distribution board is installed with conductors connected — meaning it is not touch-protected on the busbar side until the enclosure cover is on. Silicon-free construction is specified — relevant for paint-shop or potting applications where silicone outgassing can cause adhesion failures.
