Accepts solid or stranded conductors from 0.75 to 35 mm²; the screw terminals torque to 2.5–3 N·m. Mounts in any position, so it fits tight enclosures without derating for orientation. Rated for ambient -25 to +45 °C, storage -40 to +75 °C, with periodic 55 °C at 95% humidity. Halogen-free and silicon-free construction. IP20 with connected conductors. Overvoltage category III, energy limiting class 3. Sealable and touch-protected. No neutral switching — this is a straight 3P breaker.","metaTitle":"Siemens 5SL3320-7CC SENTRON MCB, 3P 20A C-curve, 4.5kA","metaDescription":"Siemens 5SL3320-7CC SENTRON 3-pole miniature circuit breaker, 20 A rated, C tripping characteristic, 4.5 kA breaking capacity per EN 60898/IEC 60947-2, 400 V AC.
