This means the same device meets the fault-current requirements of residential/commercial distribution boards (60898) and industrial panelboards (60947-2) without a separate high-breaking variant. ## C-curve trip and DC capability Rated for 400 V AC and 60 V DC (72 V DC max), this 3-pole MCB handles DC control circuits up to 60 V on each pole — useful for DC bus protection in small drives or solenoid valve banks where the supply is rectified from a 400 V AC line. ## DIN-rail mounting and dimensions Snap-on quick assembly system fits standard 35 mm DIN rail; 3 modular width units (54 mm wide) with 70 mm installation depth and 76 mm overall depth. Mounting position any, combined top and bottom terminals. The 90 mm height fits standard enclosure cutouts. No neutral switching — this is a 3-pole line-side breaker only.","metaTitle":"Siemens 5SY4330-7 SENTRON 3-Pole MCB, C-Curve, 10 kA IEC","metaDescription":"Siemens 5SY4330-7 SENTRON 3-pole MCB, C-curve, rated 10 kA (IEC 60898) / 20 kA (IEC 60947-2).
