4-pole 40 A Type A RCCB — panel fit and fault protection
The Siemens SENTRON 5SV3344-6GV01 is a 4-pole RCCB rated 40 A at 50 Hz, with a 30 mA trip threshold and Type A sensitivity. It is instantaneous and has a 10 kA SCCR.
DIN-rail footprint and mounting
Depth is 70 mm, height 90 mm. The IP20 rating applies when installed in a distribution board with conductors connected, so it is intended for enclosed panel use, not open washdown areas. Silicon-free construction (Product Feature / Silicon-Free: Yes) avoids contamination in coating or potting processes.
Thermal derating and ambient limits
Derate linearly above that: 38.1 A at 45 °C, 35.59 A at 50 °C, 32.29 A at 55 °C, 28.19 A at 60 °C, 23.3 A at 65 °C, and 17.6 A at 70 °C.
