The Siemens SENTRON 5SL4206-7RC is a 2-pole miniature circuit breaker (MCB) with a C tripping characteristic, rated 6 A and a 10 kA breaking capacity per EN 60898 at 415 V AC. It occupies a single modular width (18 mm) on a DIN rail, making it a compact fit for residential and infrastructure distribution boards where overcurrent and short-circuit protection of lighting, socket, and small appliance circuits is needed.
Breaking capacity of 10 kA at 415 V AC per EN 60898 means this MCB can safely interrupt fault currents up to 10,000 A without welding or arcing over — sufficient for most residential and light commercial service entrances where the prospective short-circuit current (PSCC) is below that threshold. The 6 A rating protects a 1.5 mm² copper conductor in a 2.5 mm² circuit, typical for lighting or general-purpose socket outlets. The 2-pole design switches both phase and neutral, which is required for single-phase circuits in many national wiring rules. The 18 mm width (1 MW) means it slots into a standard DIN-rail enclosure sharing space with other SENTRON devices.
