Product details

The Siemens 5SL4116-8 is a SENTRON miniature circuit breaker (MCB) — 1 pole, D characteristic, rated 16 A at AC. The D curve means it tolerates the high inrush of motor-starting and transformer loads without nuisance tripping, while still clearing a fault at its rated 10 kA breaking capacity per both IEC 60898 and IEC 60947-2.

Thermal derating matters on this one

At 40 °C that drops to 14.78 A, at 45 °C to 14.08 A, and at 55 °C to 12.74 A. The unit is rated for ambient up to 55 °C and 95% humidity, with storage from -40 °C to 75 °C.

Single-module width (18 mm, 1 MW) snaps onto standard DIN rail. Mounting position is unrestricted — horizontal, vertical, upside-down — so it fits tight gland-plate layouts. IP20 with conductors connected; overvoltage category III, pollution degree 2.

Frequently asked questions

What is the breaking capacity of the 5SL4116-8?

10 kA per both IEC 60898 and IEC 60947-2 — that's the same rating under both standards, so it coordinates cleanly with upstream distribution panels rated for that fault level.

Where can I buy the 5SL4116-8?

This part 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 position.

What does the D tripping characteristic mean?

The D curve (typically 10–20× In magnetic trip) is chosen for loads with high inrush current — motor starters, small transformers, discharge lamps. It avoids nuisance trips on start-up while still providing short-circuit protection at the 10 kA rating.

Will the 5SL4116-8 drop into a panel specified for 5SL6132-6MB?

Both are 1-pole SENTRON MCBs on the same DIN-rail footprint, but the 5SL6132-6MB is a B-curve 32 A unit. The 5SL4116-8 is D-curve 16 A — different rating and characteristic. Mechanically it fits the same rail and busbar system; electrically it only replaces the 5SL6132-6MB if the circuit's load and coordination study allow a lower current rating and a D curve.
