The Siemens 5SL4102-6 is a SENTRON miniature circuit breaker rated 2 A, single-pole, with a B tripping characteristic and a 10 kA breaking capacity certified to both EN 60898 and IEC 60947-2. That 10 kA rating at 400 V AC means it can safely interrupt a fault current up to 10,000 A without welding its contacts or failing catastrophically — the same figure under both standards, so it satisfies residential and light commercial distribution board requirements across Europe and markets that follow IEC 60947-2 for industrial panels.
Occupies a single 18 mm modular width unit on a DIN rail. IP20 with connected conductors, so it belongs inside a closed enclosure, not exposed to washdown.
Halogen-free and silicon-free construction.
