Instantaneous trip, no intentional delay. The 63 A rating holds flat from 40 °C to 60 °C; at 65 °C it derates to 57.35 A, at 70 °C to 48.84 A. Terminal position is top or bottom, mounting position any. Protection class IP20 with conductors connected and distribution board installed. Silicon-free construction and finger/back-of-hand safe shock protection are standard for this generation. Overvoltage category III, suitable for fixed-installation distribution boards. ## Dimensions & integration 72 mm wide (4 width units), 90 mm tall, 70 mm deep — fits standard DIN-rail enclosures with 70 mm installation depth. Neutral on the left.","metaTitle":"Siemens 5SV3746-6KL SENTRON RCCB, 63 A, 4-pole, Type A, 10 k","metaDescription":"Siemens 5SV3746-6KL SENTRON RCCB, 63 A rated, 4-pole, Type A, 10 kA short-circuit rating, 230/400 V AC.
