It is a short-time delayed design, meaning it tolerates brief surge currents (rated 3 kA) without tripping, which is useful for selectivity with downstream devices or loads with inrush. At 65 °C it drops to 57.35 A, and at 70 °C to 48.84 A. Snaps onto DIN rail (any mounting position). Depth is 70 mm, height 90 mm, width 72 mm (4 standard width units).","metaTitle":"Siemens 5SV4446-0LA01 SENTRON RCCB, 63 A, 4-pole, 10 kA","metaDescription":"Siemens SENTRON 5SV4446-0LA01 RCCB, 63 A rated, 4-pole, AC type, short-time delayed, 10 kA SCCR, 230/400 V.
