The integrated auxiliary switch (1 NO + 1 NC) gives remote status feedback without a separate accessory module, saving a DIN slot. Temperature derating is built in: at 50 °C the continuous rating drops to 4.37 A, at 60 °C to 4.02 A. Mounting position is unrestricted, and the quick-assembly system clips onto standard DIN rail with a 27 mm width — one modular unit. The 27 mm width (one modular unit) and 76 mm depth fit standard 18 mm-pitch DIN-rail enclosures. Installation depth is 70 mm, leaving clearance behind the rail for wiring. Halogen-free and silicon-free construction suits clean-room or food-grade zones where outgassing is a concern. The energy limitation class is 3, meaning it limits let-through energy under fault conditions. The product designation per IEC 81346-2 is F (protective device). Compliance documentation (declaration of conformity, CE marking) is available from the manufacturer; the part carries the SENTRON brand designation.","metaTitle":"Siemens 5SY4111-7XX02 SENTRON MCB, 5A C-Curve, 1P, 10kA","metaDescription":"Siemens 5SY4111-7XX02 SENTRON miniature circuit breaker, 5 A rated, C-curve, 1-pole, 10 kA (EN 60898) / 35 kA (IEC 60947-2).
