It occupies 2 modular width units (36 mm) on a DIN rail and is intended for DC circuits in residential and infrastructure installations. ## What the ratings mean for fit The B characteristic (tripping between 3 and 5 times rated current) is standard for resistive loads and general-purpose DC circuits where inrush is low — think lighting, control transformers, or DC bus distribution. The 10 kA breaking capacity at 250 V DC means it can safely interrupt a fault current up to that level without welding contacts or cascading failure upstream. At 2 MW (36 mm wide), it fits a standard 18 mm-per-pole DIN-rail slot; two poles means it switches both the positive and negative lines in a DC system. Rated for overvoltage category III and pollution degree 2, this MCB is suited for fixed installations inside a panel — not for outdoor or wet locations (IP20 only with conductors connected). The -40 °C to 75 °C operating range covers most unheated electrical rooms and outdoor enclosures in temperate climates. ## Panel integration notes Mounts on standard 35 mm DIN rail in any position. Depth is 76 mm overall, with 70 mm installation depth behind the panel surface. The housing is halogen-free and silicon-free — relevant for clean-room or high-reliability environments where outgassing matters. Sealable design allows locking the toggle in the off position for lockout/tagout. Supplementary devices (auxiliary switches, shunt trips, alarm contacts) can be added on the right side.","metaTitle":"Siemens 5SL5201-6CC SENTRON MCB, 2-pole B, 250 V DC, 10 kA","metaDescription":"Siemens 5SL5201-6CC SENTRON miniature circuit breaker, 2-pole, B characteristic, 250 V DC, 10 kA breaking capacity.
