Product details

Integrator's spec recap — 5SL3608-7

The Siemens 5SL3608-7 is a 4-pole (3P+N) miniature circuit breaker from the SENTRON 5SL3 series, rated 8 A with a C tripping characteristic. It breaks 4.5 kA per EN 60898 and IEC 60947-2 at 400 V AC, and handles up to 440 V AC in multi-phase operation. Terminals accept solid or stranded conductors from 0.75 to 25 mm², tightened to 2.5–3 N·m. The neutral pole switches, which matters for 3P+N distribution panels where you want a single-break device rather than a separate neutral link. Touch protection is built in; IP20 applies with conductors connected.

The 4-pole design occupies 4 width units (72 mm), so plan for that in your panel fill factor. The sealable feature (padlockable toggle) allows lockout/tagout without an external hasp — useful for MRO isolation procedures.

Frequently asked questions

Where can I buy 5SL3608-7 and what is the lead time?

The 5SL3608-7 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is 5SL3608-7's depth and how does it affect panel fit?

The overall depth is 76 mm, with an installation depth of 70 mm behind the panel. That 6 mm difference accounts for the toggle and terminal protrusion — standard for DIN-rail MCBs, but check your enclosure depth if you have less than 80 mm clearance.

What conductor sizes does 5SL3608-7 accept?

The terminals accept solid and stranded conductors from 0.75 mm² up to 25 mm². That covers most branch-circuit wiring from 1.5 mm² lighting circuits up to 6 mm² feeder tails.

Will 5SL3608-7 drop into a panel specified around 5SL6563-7BB without rewiring?

Both are 4-pole SENTRON MCBs on the same DIN-rail footprint, so the mechanical swap is straightforward. The key difference is rating — verify your load current and breaking capacity requirements against the 8 A C-curve and 4.5 kA of the 5SL3608-7 before substituting.

What compliance documentation does Siemens provide for 5SL3608-7?

The product carries EN 60898 and IEC 60947-2 ratings, is halogen-free and silicon-free, and is marked per DIN EN 61346-2 and DIN EN 81346-2. Standard Siemens declarations of conformity and material compliance (RoHS, REACH) are available on request.
