The 1P+N construction switches both line and neutral, with the neutral pole opening and closing with the line pole. This is required in some regional wiring rules (e.g., UK, Australia, parts of the Middle East) where the neutral must be disconnected on the same device. The neutral pole is not overcurrent-protected — it tracks the line pole mechanically. Mounts on standard DIN rail, occupies one 18 mm width unit, torque range 17.7 to 22.1 lbf·in. IP20 with connected conductors. 18 mm width and 76 mm depth match the SENTRON family footprint. Installs in any mounting position on DIN rail, installation depth 70 mm. Halogen-free and silicon-free construction means no corrosive off-gassing during a fault arc — relevant for panels housing sensitive electronics or in clean-room adjacent spaces. Energy limiting class 3 means this MCB limits the let-through energy (I²t) to a low level, aiding downstream coordination with smaller branch breakers or fuses. In a typical distribution board, the 5SY3032-7WM as a sub-feed breaker will coordinate with a 32 A or smaller load-side MCB — but full selectivity tables from the manufacturer should be consulted for the specific upstream device.","metaTitle":"Siemens 5SY3032-7WM SENTRON MCB, 32 A C-Curve 1P+N","metaDescription":"Siemens SENTRON 5SY3032-7WM miniature circuit breaker, 32 A rated current, C tripping characteristic, 4.5 kA breaking capacity per EN 60898, 1P+N, 18 mm wide.
