What the ratings mean for fit
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 10 kA SCCR tells you the device can safely interrupt a fault current up to 10 kA without rupturing — this is the standard breaking capacity for final sub-circuits in most residential and light commercial distribution boards. The let-through current is limited to 5 200 A, and the permissible I²t is 58 000 A²·s, which helps with downstream coordination.
Panel integration and mounting
Mounts on DIN rail (REG) per; 2 modular width units (36 mm wide,) at 60 mm grid spacing. Depth is 70 mm, height 90 mm. Installation depth matches the depth dimension. Supply can enter from top or bottom; mounting position is unrestricted. 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.
