The Siemens 5SL1232-6MB is a SENTRON miniature circuit breaker — 2-pole, B-curve, rated 32 A, with a 3 kA breaking capacity per IEC 60947-2. It's designed for residential and infrastructure branch circuits where the B-curve (3–5× In magnetic trip) protects lighting, socket outlets, and general-purpose loads with low inrush. The 32 A rating covers heavier final circuits like electric water heaters or large socket groups.
IP20 with connected conductors; overvoltage category III, pollution degree 2. Sealable, halogen-free, silicon-free. Mechanical life is 4 000 operating cycles typical — adequate for residential/infrastructure duty where switching frequency is low.
