Integrator's note — 5SY6632-7CC
The Siemens 5SY6632-7CC is a SENTRON miniature circuit breaker, 4-pole (3P+N), with a C tripping characteristic rated at 32 A at 35 °C. Breaking capacity is 6 kA per EN 60898 and 5 kA per UL 1077 / CSA C22.2 No.235. It occupies 4 modular width units (72 mm) on a DIN rail and mounts in any position. The combined terminals top and bottom accept the quick assembly system, and the unit is sealable for tamper-proof installations. Rated current derates with ambient temperature: 30.5 A at 40 °C, 29.7 A at 45 °C, 28.9 A at 50 °C, and 28.06 A at 55 °C. The C-curve means magnetic trip occurs at 5 to 10 times rated current — suited for motor-starting and transformer inrush where a B-curve would nuisance-trip. Pollution degree 3 and overvoltage category III qualify it for industrial control panels, not just residential distribution.
Panel integration
Mounts on a 35 mm DIN rail per the quick assembly system. Depth is 76 mm (installation depth 70 mm), height 90 mm. The 4 MW width (72 mm) means it occupies four adjacent 18 mm slots — verify fill factor against the gland plate before laying out the row. IP20 with connected conductors; no washdown rating, so keep it inside a sealed enclosure in wet environments. Ambient operating range is -40 °C to 75 °C, with humidity limits of 95% at 55 °C, 55% at 70 °C, and 35% at 75 °C.
