Integrator note
The Siemens 5SY4316-7 is a 3-pole SENTRON miniature circuit breaker with C-curve tripping characteristic, rated 400 V AC (440 V max) and 60 V DC (72 V max). Breaking capacity reaches 10 kA per EN 60898, 20 kA per IEC 60947-2, and 5 kA per UL1077 — the UL figure governs North American panel listings. DC rating is 15 kA at 60 V per IEC 60947-2, so verify the system voltage and prospective fault current before committing the BOM line.
IP20 with connected conductors; pollution degree 3 suits industrial environments. Combined top and bottom terminals simplify daisy-chaining.
Halogen-free and silicon-free construction, sealable for tamper-proof installations. Ambient temperature range -40 to 75 °C, with humidity derating above 55 °C (max 95% RH at 55 °C, 55% at 70 °C, 35% at 75 °C). Overvoltage category III, energy limitation class 3. Neutral conductor is not switched — this is a 3-pole device for line-side protection only.
