At 65 °C it derates to 57.35 A, and at 70 °C to 48.84 A. The I²t let-through is rated 110 000 A²s, and surge current resistance is 1 kA — both figures govern coordination with upstream MCBs or fuses during fault events. Mounts on DIN rail (REG) in any position — top or bottom feed. Depth is 70 mm, height 90 mm, width 72 mm (4 width units). IP20 with conductors connected and the distribution board installed; finger and back-of-hand safe per the protection class. Neutral is on the left (N left variant). The minimum test voltage is 100 V. Overvoltage category III, suitable for fixed-installation distribution boards.","metaTitle":"Siemens 5SV3646-6KL RCCB, 63 A, 4-pole, Type A, 10 kA","metaDescription":"Siemens 5SV3646-6KL SENTRON RCCB, 63 A rated, 4-pole, Type A, 10 kA SCCR, 230/400 V, DIN rail.
