Mounting position doesn't matter — any orientation works. Feeds can land top or bottom, which saves time when you're wiring a crowded enclosure and the gland plate is already full. The silicon-free construction matters if you're putting it in a panel near potting or coating processes where silicone outgassing can cause contact issues. Rated current holds at 63 A from 40 °C up to 55 °C; it starts to derate above that — 57.35 A at 65 °C, 48.8 A at 70 °C. The let-through energy (I²t) is rated at 110,000 A²·s, and surge current resistance is 1 kA. Overvoltage category III means it's suited for fixed-installation distribution boards, not just downstream equipment.","metaTitle":"Siemens 5SV3346-6LA SENTRON RCCB, 4P, 63 A, 30 mA, Type A","metaDescription":"Siemens 5SV3346-6LA SENTRON 4-pole RCCB, 63 A rated, 30 mA trip, Type A, 10 kA SCCR.
