The Siemens 5SL6202-7MB is a 2-pole miniature circuit breaker from the SENTRON 5SL series, rated 2 A with a C tripping characteristic. It is designed for residential and infrastructure branch-circuit protection at 400 V AC, with a 6 kA breaking capacity according to EN 60898 — sufficient for most domestic and light commercial distribution boards where the prospective fault current stays under that threshold. The C-curve means the magnetic trip operates at 5 to 10 times the rated current (10–20 A), which suits loads with moderate inrush, like lighting circuits, small transformers, and general-purpose socket outlets. The 2-pole configuration switches both phase and neutral (or two phases) in a single-width 36 mm housing — 2 modular width units on a DIN rail. Rated for 400 V AC between phases and 250 V AC single-phase, with a maximum operating voltage of 440 V AC. The mechanical service life is 10,000 operating cycles typical, and the power loss per pole is 1.25 W at rated current in hot state — negligible for panel thermal budgeting.
Width is 36 mm (2 MW). Sealable design allows tamper-proof locking after commissioning. Halogen-free and silicon-free construction, suitable for environments where off-gassing must be minimized (clean rooms, critical infrastructure). Degree of pollution 2 and overvoltage category III — standard for fixed-installation switchgear.
