The 2 A rated current and B curve mean this MCB trips between 3 and 5 times rated current (6–10 A) on short circuits — standard for lighting and general-purpose loads where no high inrush exists. IP20 with connected conductors means the breaker itself is finger-safe but not protected against moisture or dust ingress; it belongs inside a closed panel or distribution board. Snap-on DIN rail mount, any orientation. 3 width units (54 mm wide) with a total depth of 76 mm and installation depth of 70 mm — standard for a 3-pole MCB in a SENTRON distribution board. Screw terminals accept solid or stranded copper from 0.75 to 25 mm²; tighten to 2.5–3 N·m. Sealable housing and touch protection are built in, which helps with lockout/tagout compliance and prevents accidental contact with live busbars.","metaTitle":"Siemens 5SL4302-6CC SENTRON MCB, 3P, 2 A, B Curve, 10 kA","metaDescription":"Siemens 5SL4302-6CC SENTRON miniature circuit breaker, 3-pole, 2 A, B characteristic, 10 kA breaking capacity per EN 60898.
