Product details

The 5SL4325-6: The B curve (tripping between 3 and 5 times rated current) is the standard choice for residential and light commercial lighting and socket-outlet circuits — it's not for motor starting or transformer inrush, where a C or D curve would be needed. The 10 kA breaking capacity is rated per both EN 60898 and IEC 60947-2, so it's accepted across domestic and industrial distribution boards alike. At 400 V AC three-phase, it covers most European panel voltages; the maximum operating voltage is 440 V AC.

Depth is 76 mm, installation depth 70 mm — it clears a standard 80 mm deep enclosure without gland-plate interference. Mounting position any, which helps when the panel layout is tight.

Frequently asked questions

What is the breaking capacity of the 5SL4325-6?

10 kA rated per both EN 60898 and IEC 60947-2 at 400 V AC.

Will the 5SL4325-6 drop into a panel specified for the 5SL4363-7?

Yes — same 3-pole footprint, same 54 mm width, same 76 mm depth, same DIN-rail mounting. The only difference is the trip curve: B on the 5SL4325-6 versus C on the 5SL4363-7. If the panel was designed for a C-curve breaker, swapping to a B-curve may cause nuisance tripping on loads with higher inrush.

Where can I buy the 5SL4325-6?
