Characteristic A is the key differentiator here. Most panel spares are B or C curve; this one opens faster on overload and short-circuit, which makes it the right choice for protecting sensitive electronics, control transformers, or semiconductor rectifiers where a B-curve's 3–5x In window would let a fault ride through long enough to damage downstream gear. The 4 A rating derates with ambient temperature — at 40 °C it's 3.76 A, at 50 °C it's 3.5 A, at 60 °C it's 3.22 A — so if the breaker lives in a warm cabinet, size up accordingly. The 2 MW (36 mm) width means it occupies two standard 18 mm DIN positions. Mounts on DIN rail in any orientation. Designed to IEC/EN 60898-1 and IEC/EN 60947-2, with UL1077 recognition. Halogen-free and silicon-free construction. Suitable for mechanical engineering and general industry per the manufacturer's classification. The EN 61346-2 and IEC 81346-2 function code is F (protective device).","metaTitle":"Siemens 5SY4504-5 SENTRON MCB, 4A, Char A, 2-Pole, 10kA","metaDescription":"Siemens 5SY4504-5 SENTRON miniature circuit breaker, 4A rated, tripping characteristic A, 2-pole (1P+N), 10kA breaking capacity per EN 60898.
