The Siemens 5SL6205-7CC is a SENTRON miniature circuit breaker (MCB) with a 2-pole design, C tripping characteristic, and a rated current of 0.5 A at 400 V AC. Its 6 kA breaking capacity is certified per EN 60898, making it suitable for residential and infrastructure branch-circuit protection where short-circuit levels stay within that threshold.
What the ratings mean for fit
The C-curve (tripping characteristic class C) means the magnetic trip operates at 5 to 10 times rated current — appropriate for circuits with moderate inrush, such as lighting banks or small transformers. At 0.5 A, this is a low-current branch breaker, not a feeder or motor-circuit device. The 6 kA breaking capacity per EN 60898 defines the maximum prospective fault current the breaker can safely interrupt at 400 V AC. For installations where the available fault current exceeds 6 kA, a current-limiting upstream device or a higher-rated breaker (e.g., 10 kA per IEC 60947-2) would be required. Rated for overvoltage category III and pollution degree 2, this MCB is designed for fixed-installation distribution boards within a building's main or sub-distribution — not for outdoor or wet-location panels without additional enclosure protection.
Panel integration and mounting
Occupies 2 modular width units (36 mm) on a DIN rail. Installation depth is 70 mm; overall depth including terminals is 76 mm. Mounting position is unrestricted — the breaker operates correctly in any orientation. IP20 rating applies only with connected conductors — the terminals are finger-safe when wired, but the breaker itself is not sealed against dust ingress or moisture. Sealable design allows locking in the OFF position for lockout/tagout compliance. Supplementary devices (auxiliary switches, shunt trips, alarm contacts) can be installed on the side, per the product extension feature. Power loss is 0.9 W per pole at rated current in hot operating state — negligible for thermal budgeting in a populated distribution board.
