Energy limiting class 3 means it restricts let-through energy on a fault, reducing stress on downstream components and busbars. Rated for overvoltage category III (fixed installation), this MCB is suitable for permanent connection in distribution panels where transient overvoltages from the mains are expected. Humidity derating is specified: max 95% RH at 55 °C, dropping to 55% at 70 °C and 35% at 75 °C — relevant if the panel sits in a humid plant near steam or washdown zones. The screw-type terminals accept 0.75–35 mm² solid or stranded wire; tighten to 2.5–3.5 N·m. The neutral pole is switched (1P+N), so this breaker disconnects both line and neutral on a fault — required for single-phase final circuits in many IEC markets. Sealable with a lockout tagout hasp. Touch protection is built in (finger-safe terminals when wired).","metaTitle":"Siemens 5SY4508-7CC11 SENTRON MCB, 2-pole 8A C-curve, 10kA","metaDescription":"Siemens 5SY4508-7CC11 SENTRON miniature circuit breaker, 2-pole 1P+N, 8A rated, C tripping characteristic, 10kA breaking capacity per EN 60898, 230V AC.
