It is rated for 400 V AC supply voltage and breaks fault currents up to 6 kA per EN 60898 or 10 kA per IEC 60947-2 — the higher IEC figure gives you headroom for industrial panel coordination where the standard requires the 60947-2 rating. The 72 V DC maximum rating means it also handles DC control circuits, though the primary duty is AC branch protection. ## What the breaking capacities mean for your panel Two breaking capacity ratings are listed because they certify against different standards. The 6 kA figure per EN 60898 is the residential/commercial standard — sufficient for most building distribution boards. If your panel spec calls out IEC 60947-2 coordination, this breaker delivers the full 10 kA without needing an upstream current-limiting device. The 4-pole configuration with neutral switching (3P+N) suits TN and TT systems where you want to isolate all live conductors. Depth is 76 mm (70 mm installation depth behind the panel surface), height 90 mm, width 72 mm occupying 4 modular units. Accepts solid conductors up to 35 mm². Power loss is 6 W per pole in hot operating state at rated current. ## Sourcing posture","metaTitle":"Siemens 5SN6463-7CP MCB, 4-Pole C-Curve, 6/10 kA","metaDescription":"Siemens 5SN6463-7CP 4-pole MCB, C-curve, 6 kA (EN 60898) / 10 kA (IEC 60947-2), 400 V AC, 72 V DC.
