Characteristic E means it's designed for moderate inrush currents — a fit for motor starter or transformer primary protection where the trip curve sits between B and K. Rated 400 V AC, overvoltage category IV, pollution degree 3. Snap-on standard rail mounting, 4.5 modular width units. Sealable with integrated locking slide — lock, wire seal, or cable tie. Accepts solid or stranded conductors up to 50 mm², down to 2.5 mm². Saddle terminals, infeed at box terminal. IP40 with connected conductors. Ambient range -40 °C to 70 °C; derate the 35 A rating above 30 °C (33.25 A at 40 °C, 31.5 A at 50 °C). Snaps onto standard DIN rail (fastening method: standard rail). Depth 76.3 mm, height 128 mm — fits standard distribution boards. 4.5 MW units wide. Lockable with integrated slide; sealable. Saddle terminals accept 2.5–50 mm² solid or stranded. Infeed at box terminal. Power supply cord position any — no orientation restriction.","metaTitle":"Siemens 5SP3835-3 SENTRON MCB, 3P, 35A, 25kA, Char E","metaDescription":"Siemens SENTRON 5SP3835-3 miniature circuit breaker, 3-pole, 35 A rated, 25 kA breaking capacity, characteristic E.
