Product details

The Siemens SENTRON 5SL6116-6MB is a 1-pole miniature circuit breaker with a B tripping characteristic, rated 16 A at 30 °C and 400 V AC supply voltage.

The B-curve trips between 3 and 5 times rated current — 48 to 80 A for this 16 A unit — making it a fit for resistive and general-purpose loads where inrush isn't severe. The 6 kA breaking capacity at 230/400 V AC is enough for most residential and light commercial distribution boards; if your fault level at the panel is higher, you'd step up to the 10 kA variant in the same 5SL6 family.

The -40 °C to 75 °C operating range covers unheated utility rooms and outdoor-adjacent enclosures. Touch protection on the terminals is built in; no finger-safe covers needed.

Frequently asked questions

Where can I buy 5SL6116-6MB and how do I get a price?

The 5SL6116-6MB is sourced and quoted 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.

When sourcing 5SL6116-6MB, what's the closest functional second-source — 5SL3116-6MB?

The 5SL3116-6MB is the closest peer: same 1-pole B-curve 16 A rating, same 18 mm footprint, but with a 4.5 kA breaking capacity instead of the 5SL6116-6MB's 6 kA. It drops into the same panel position without rewiring, but verify the fault level at the board — if you need 6 kA, the 5SL6116-6MB is the correct call.

Will 5SL6116-6MB drop into a panel that was specified around 5SL3116-6MB without rewiring?

Yes — both share the same 18 mm width, 76 mm depth, and DIN-rail mounting. The 5SL6116-6MB is a direct mechanical swap for the 5SL3116-6MB. No rewiring or busbar adjustment needed; just confirm the higher 6 kA breaking capacity is compatible with your installation's prospective fault current.

What compliance documentation does this brand provide for 5SL6116-6MB?

The 5SL6116-6MB is rated per EN 60898 for breaking capacity, carries overvoltage category III and pollution degree 2 ratings, and is designed for residential/infrastructure suitability. The SENTRON series typically provides CE, RoHS, and REACH declarations — consult the product documentation for specific certificates.
