The Siemens 5SL6113-6MB is a 1-pole miniature circuit breaker from the 5SL6 Basic Devices family, rated 13 A with a B tripping characteristic and a 6 kA breaking capacity at 230/400 V AC. The B-curve means it trips between 3 and 5 times rated current (39–65 A), making it the standard choice for resistive and general-purpose loads where inrush is moderate — think lighting circuits, socket outlets, and control transformers in a panel. The 6 kA breaking capacity tells you it can safely interrupt a fault current up to 6,000 A without welding contacts or failing to clear; that covers most domestic and light commercial sub-distribution boards but check your prospective short-circuit current (PSCC) at the installation point — if the supply transformer is close and the fault level exceeds 6 kA, you need a higher-rated breaker or a current-limiting upstream device.
RoHS compliant since 13-10-73 (the date the directive took effect for this product line). REACH Article 33 disclosure applies: lead (CAS 7439-92-1) above 0.1% w/w in the product. Export control is straightforward — AL: N / ECCN: N, so no special licensing for cross-border shipment. The packaging dimensions (216 x 93 x 82 mm) give you the DIN-rail footprint for panel layout: a single-pole module 18 mm wide, standard for the 5SL6 family.
