The C-curve (5-10x In) handles motor and lighting inrush without nuisance tripping on start-up, which is the usual call for this class of MCB. Lifecycle status is marked as current production. That means this order code is still the active catalog number — no phase-out notice, no last-time-buy clock running. Mounts on DIN rail in any orientation — the mounting position is unrestricted. Installation depth is 70 mm, and it occupies 4 width units (about 72 mm of rail space). Rated insulation voltage is 440 V AC, with an overvoltage category of 3 — standard for fixed-installation distribution boards. Ambient operating range is -20 to +45 °C, with a storage range of -40 to +75 °C. Mechanical endurance is rated at 20 000 switching cycles typical. Vibration resistance is tested to IEC 60068-2-6 at 50 m/s² from 25 to 150 Hz.","metaTitle":"Siemens SENTRON 5SJ3632-7 MCB, 32A 4.5kA C-Curve 4P","metaDescription":"Siemens SENTRON 5SJ3632-7 miniature circuit breaker, 32 A rated, 4.5 kA breaking capacity per EN 60898, C-curve, 3P+N, 400 V AC.
