The Siemens 5SL6102-7BB is a 1-pole miniature circuit breaker from the SENTRON family, rated 2 A with a C tripping characteristic and a 6 kA breaking capacity per both EN 60898 and IEC 60947-2. It snaps onto a DIN rail in a standard distribution board or sub-panel — one modular width (18 mm) wide, 90 mm tall, 76 mm deep, with an installation depth of 70 mm. The C-curve means it handles moderate inrush currents typical of lighting circuits, small transformers, and control loads without nuisance tripping, while still clearing faults up to 6 kA at 230/400 V AC.
The 2 A rating is the continuous current at 30 °C ambient; at 40 °C it derates to 1.92 A, at 45 °C to 1.88 A, and at 55 °C to 1.79 A — so if the panel runs hot, the actual load limit drops. The 6 kA breaking capacity under both EN 60898 (household standard) and IEC 60947-2 (industrial standard) means it can safely interrupt a fault current up to 6 kA at the rated voltage without welding contacts or cascading failure upstream.
Mounts in any position on DIN rail. Sealable so a padlock or seal can lock the toggle position for lockout/tagout.
