The characteristic A curve trips instantaneously on short-circuit, with a narrow magnetic threshold (typically 2–3 In), so it is suited for protecting sensitive semiconductor loads or long cable runs where low let-through energy matters. Rated 400 V AC (440 V multi/single-phase) and 60 V DC (72 V max), it fits standard 230/400 V distribution panels and DC control circuits up to 60 V nominal. The 5SY4101-5 is certified to IEC/EN 60898-1 (household-type MCB) and IEC/EN 60947-2 (industrial MCB), plus UL 1077 and CSA C22.2 No. 235 for the North American supplementary protector market. The UL 1077 rating is 5 kA, which is the standard for supplementary protectors in control panels. Pollution degree 3 (conductive pollution) and overvoltage category III (fixed installation) confirm it for industrial environments. The part is halogen-free and silicon-free, meeting clean-room and low-outgassing requirements. Vibration resistance per IEC 60068-2-6 covers ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz — suitable for machine-mounted panels. Sealable, so a panel builder can lock the toggle position after commissioning. No neutral conductor switching (1-pole only). ## Environmental range Operating ambient -40 to 75 °C, with derating above 55 °C: max 95% RH at 55 °C, 55% at 70 °C, 35% at 75 °C. This covers cold storage and hot panel interiors, but the humidity derating curve means the breaker should not be in a condensing environment above 55 °C.","metaTitle":"Siemens 5SY4101-5 SENTRON MCB, 1P, Characteristic A, 10 kA","metaDescription":"Siemens 5SY4101-5 SENTRON miniature circuit breaker, 1-pole, characteristic A, 10 kA per EN 60898, 35 kA per IEC 60947-2.
