Product details

The 5SL6305-7MB: The C-curve trips between 5 and 10 times rated current — right for moderate inrush loads like small motors or lighting panels on a 0.5 A branch.

Depth is 76 mm, width 54 mm (3 MW), installation depth 70 mm. IP20 with connected conductors — fine inside an enclosed panel, not for wet environments.

Frequently asked questions

Where can I buy the 5SL6305-7MB?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

Will 5SL6305-7MB drop into a panel that was specified around 5SL4363-7 without rewiring?

Yes — the 5SL6305-7MB shares the same 76 mm depth, 54 mm width, 3 MW DIN-rail footprint, and 3-pole design as the 5SL4363-7, so it fits the same panel cutout and busbar arrangement. The main difference is breaking capacity: the 5SL6305-7MB is rated 6 kA per EN 60898, while the 5SL4363-7 is rated 10 kA per both EN 60898 and IEC 60947-2.

What compliance documentation does Siemens provide for 5SL6305-7MB?

The breaker is halogen-free and silicon-free. It carries the designation per EN 61346-2 and IEC 81346-2 (code F). The manufacturer provides standard CE declaration and RoHS/REACH documentation on request.
