Product details

Rated for 50/60 Hz, it fits standard mains supplies.

Occupies 3 modular-width units (54 mm wide) on a DIN rail.

The closest functional peer in the same SENTRON family is the 5SL4363-7. Both are 3-pole, C-curve, same 76 mm depth and 54 mm width, same operating temperature range, same vibration resistance. The difference is breaking capacity: the 5SL4363-7 is rated 10 kA per EN 60898 and IEC 60947-2, while this 5SL6350-7MB is rated 6 kA per EN 60898. If your panel's prospective fault current is under 6 kA, the 5SL6350-7MB is the correct fit; if you need 10 kA headroom, step up to the 5SL4363-7.

Frequently asked questions

Where can I buy 5SL6350-7MB?

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

Will 5SL6350-7MB drop into a panel specified around 5SL4363-7 without rewiring?

Yes — both share the same 54 mm width, 76 mm depth, DIN-rail mounting, and 3-pole form factor, so a direct swap is possible. The only difference is the 6 kA vs 10 kA breaking capacity; verify your fault level before substituting.

What is the depth and width of 5SL6350-7MB?

Depth is 76 mm, width is 54 mm (3 modular units), height is 90 mm.
