It carries a 15 kA breaking capacity per IEC/EN 60947-2, making it suitable for branch-circuit protection in industrial control panels and distribution boards where the fault level stays under that threshold. ## Ratings and what they mean for fit The C-curve means the magnetic trip operates at 5 to 10 times rated current — standard for motor circuits, transformers, and lighting loads with moderate inrush. At 32 A it handles a 7.5 kW three-phase motor at 400 V without nuisance tripping on startup. Breaking capacity of 15 kA at 440 V AC is the maximum fault current the breaker can safely interrupt. Temperature derating is published: 32 A at 35 °C, 30.24 A at 40 °C, 29.31 A at 45 °C, 28.4 A at 50 °C, 27.36 A at 55 °C (–). If the breaker lives in a non-air-conditioned enclosure, size up one frame or account for the drop at your ambient. Neutral conductor switching is built in — the fourth pole switches the neutral, not just the phases. That matters for TN-S or TT systems where the neutral must be isolated when the breaker opens. ## Mounting and panel integration Snap-on mounting to 35 mm DIN rail per the quick assembly system. Occupies 4 modular width units — 72 mm wide. Depth behind the panel is 70 mm; overall depth 76 mm. Mounting position any, so vertical or horizontal busbars both work. IP20 with connected conductors — protected against finger contact but not water ingress. Fine for enclosed distribution boards; not for washdown environments. Combined terminal top and bottom accept both busbar and cable entry without swapping parts. Sealable for lockout/tagout compliance. ## Environmental and compliance Halogen-free and silicon-free construction — relevant for clean-room or sensitive electronic environments where outgassing can cause contact corrosion. Vibration resistance tested per IEC 60068-2-6: ±1 mm at 5 to 25 Hz, 50 m/s² at 25 to 150 Hz. Mechanical service life 10,000 switching cycles typical. Overvoltage category III, pollution degree 3 — suitable for fixed installations in industrial environments with conductive pollution.","metaTitle":"Siemens 5SY4632-7CV MCB, 4P C-32 A 15 kA IEC 60947-2","metaDescription":"Siemens 5SY4632-7CV 4-pole MCB, C-curve 32 A, 15 kA breaking capacity per IEC 60947-2.
