The 5SY6CC design includes touch protection and is sealable for tamper-evident metering or rental applications. The D-curve is the key selector here. Unlike a B-curve (lighting, resistive) or C-curve (general-purpose), D-curve allows 10–20× rated current for a short duration before tripping magnetically. That's what you need when the load is a motor, a power supply bank, or a transformer — the inrush won't pop the breaker on energization. The 32 A rating at 400 V AC three-phase gives you about 22 kW of connected motor load (assuming 0.85 PF), which is a solid mid-range feeder or a large individual motor circuit. Breaking capacity is 6 kA per EN 60898 and 5 kA per UL 1077 / CSA C22.2 No. 235. If your installation is in a North American panel with a higher available fault current, the 5 kA UL figure is the binding limit — verify your SCCR before committing. The 72 V DC maximum rating means this MCB can switch DC control circuits up to that voltage, but it's primarily an AC device. ## Panel integration checklist Depth is 76 mm, height 90 mm, width 72 mm (4 MW). Installation depth into the enclosure is 70 mm — the extra 6 mm is the terminal overhang. Combined terminals top and bottom mean you can feed from either direction.","metaTitle":"Siemens 5SY6432-8CC SENTRON MCB, 4P D-32A, 6kA","metaDescription":"Siemens 5SY6432-8CC SENTRON 4-pole MCB, 32 A, D-curve, 6 kA (EN 60898), 400 V AC.
