Rated voltage is 400 V AC, insulation voltage 440 V. The 25 A C-curve is the default choice for mixed resistive and inductive loads in distribution subboards. Mounts on DIN rail with any orientation; installation depth is 70 mm. The 4 width units (72 mm) occupy four modular spaces on the rail — confirm your enclosure fill factor before committing. For a 25 A frame, expect the magnetic trip to hold steady through a motor start surge up to roughly 250 A before instantaneously opening. The 20 000 mechanical switching cycles typical service life is adequate for normal switching duty; for frequent switching (e.g., heater cycling), consider a contactor instead. Ambient temperature range is -20 to +45 °C; above 45 °C derate per the thermal curve. Storage range extends to -40 to +75 °C.","metaTitle":"Siemens SENTRON 5SJ3625-7 MCB, 25A C-Curve 3P+N 4.5kA","metaDescription":"Siemens SENTRON 5SJ3625-7 miniature circuit breaker, 25 A, C-curve, 3P+N, 4.5 kA breaking capacity per EN 60898.
