Three poles, three width units (54 mm wide). Wire range is 0.75 to 25 mm² solid or stranded, terminated under screw terminals torqued to 2.5–3 N·m. Ambient temperature range -25 to +45 °C, with periodic excursions to +55 °C at up to 95% humidity. ## What the D-curve and 6 kA mean for your panel The D tripping characteristic means the magnetic trip fires at 10 to 20 times rated current (320 to 640 A for this 32 A unit). That delay is intentional — it lets motor starting current and transformer inrush pass without opening. The trade-off: on a hard fault, the breaker lets more energy through before it clears, so the downstream cable and equipment must be rated for the let-through. ## Panel integration Mounting position any orientation.","metaTitle":"Siemens 5SN6332-8CN SENTRON MCB, 3P D 32A 6kA 400V","metaDescription":"Siemens SENTRON 5SN6332-8CN miniature circuit breaker, 3-pole, D-curve, 32 A, 6 kA breaking capacity at 400 V AC.
