Product details

Siemens 5SL4306-6 SENTRON MCB — 3-pole, B-curve, 6A, 10kA

The 5SL4306-6 occupies 3 modular width units (54 mm) on a DIN rail, with a depth of 76 mm and a height of 90 mm. The 54 mm width means it fills three 18 mm slots — standard for a 3-pole MCB in a SENTRON distribution board. Mounting position is any, so vertical or horizontal rail orientation works within the enclosure. IP20 with connected conductors — the terminals are finger-safe only when wired; the breaker itself is intended for inside a locked or tool-accessible enclosure, not exposed to washdown.

Electrical and environmental ratings

DC rated maximum is 72 V. Overvoltage category III, pollution degree 2 — standard for fixed-installation distribution panels. Halogen-free and silicon-free construction, sealable (can be locked in OFF position).

Frequently asked questions

Where can I buy the 5SL4306-6 and get a price?

The 5SL4306-6 is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is the breaking capacity of the 5SL4306-6?

The 5SL4306-6 provides a 10 kA breaking capacity per both EN 60898 and IEC 60947-2 at 400 V AC.

Will the 5SL4306-6 drop into a panel specified around the 5SL4363-7?

Yes, the 5SL4306-6 shares the same 3-pole form factor, 54 mm width, 76 mm depth, and DIN-rail mounting as the 5SL4363-7. The only difference is the tripping curve — B on the 5SL4306-6 versus C on the 5SL4363-7 — so it will physically fit without rewiring, but verify the curve matches the load type.

What compliance documentation does Siemens provide for the 5SL4306-6?

The 5SL4306-6 is certified to EN 60898 and IEC 60947-2. It is halogen-free and silicon-free. Standard Siemens documentation includes a CE declaration of conformity and RoHS/REACH compliance statements available through the product support portal.
