Product details

SENTRON 5SJ6 — 2-pole B-curve MCB at 6 A

The Siemens 5SJ6206-6 is a 2-pole miniature circuit breaker from the SENTRON 5SJ6 family, rated 6 A with a B-curve tripping characteristic. It breaks fault currents up to 6 kA per EN 60898 and IEC 60947-2 at 400 V AC, making it a standard choice for final-circuit protection in residential and light commercial distribution boards. At 6 A, it protects a 1.5 mm² or 2.5 mm² copper circuit under typical IEC installation rules.

Wire termination and panel fit

Terminals accept solid or stranded conductors from 0.75 mm² up to 25 mm². Installation depth is 70 mm; width is 2 modules. Mounting position is unrestricted, which simplifies layout in tight cabinets.

Frequently asked questions

Will 5SJ6206-6 drop into a panel specified around 5SJ6216-6 without rewiring?

Yes — the 5SJ6206-6 and 5SJ6216-6 share the same mechanical footprint (2-pole, 2-module width, 70 mm depth), same terminal wire range (0.75–25 mm² solid/stranded), and same B-curve. The only difference is the 6 A rating versus 16 A. If the panel was wired for a 16 A circuit, dropping in a 6 A breaker protects a smaller load but the physical swap is direct.
