Three-pole construction (3P) with 4.5 width units on a standard mounting rail. The 92 mm installation depth and tunnel terminals top and bottom accept solid or stranded conductors from 0.75 to 50 mm² (AWG 14 to 2). Tightening torque spec is 2.5 to 3.5 N·m (22 to 31 lbf·in) — use a torque screwdriver; under-torqued terminals are the leading cause of thermal trips in the field. Overvoltage category 3 per IEC 60947-2, meaning it's rated for fixed-installation duty with transient overvoltages typical of distribution panels. Ambient temperature range -25 to +45 °C operating, -40 to +75 °C storage. Halogen-free and silicon-free construction, which matters for installations with strict outgassing requirements (clean rooms, medical facilities, or sealed enclosures where corrosive byproducts from a fault event must be minimized). Touch protection integrated into the design. ## Mechanical endurance and environmental tolerance Rated for 20,000 mechanical switching cycles typical. Shock resistance tested to 150 m/s² at 11 ms half-sine (IEC 60068-2-27), vibration resistance to 50 m/s² at 25 to 150 Hz and 60 m/s² at 35 Hz for 4 seconds (IEC 60068-2-6). These ratings confirm the breaker holds calibration and doesn't nuisance-trip under the vibration levels common in industrial machinery or transport applications. Mounting position any, so it can be installed sideways or upside-down in a tight enclosure without derating. Periodic ambient tolerance to +55 °C and up to 95% humidity — covers most non-condensing indoor environments.","metaTitle":"SENTRON 5SP9332-7KC47 Miniature Circuit Breaker, 3P C 32A 50","metaDescription":"SENTRON 5SP9332-7KC47 miniature circuit breaker, 3-pole, C-curve, 32 A, 50 kA breaking capacity per IEC 60947-2.
