Product details

What this 1-pole 16 A MCB is for

The Siemens 5SJ4116-6HG40 is a 1-pole miniature circuit breaker from the SENTRON 5SJ4 series, rated 16 A at both 30 °C and 40 °C ambient. The IP20 enclosure (IP40 at the handle) suits it for enclosed distribution boards where accidental contact with live busbars is prevented by the cabinet door.

At 30 °C and 40 °C the breaker holds its full 16 A rating; above that it derates — 15.5 A at 45 °C, 15 A at 50 °C, 14.5 A at 55 °C, and 14.1 A at 60 °C. The DC rating maxes at 60 V, so this is a single-pole DC breaker for 24 V or 48 V control circuits, not for 125 V DC traction battery strings. Overvoltage category 3 and pollution degree 3 mean it's rated for fixed installations inside industrial panels where transient surges and conductive dust are normal.

Frequently asked questions

What is the closest functional second-source — 5SL4363-7?

The 5SL4363-7 is a different Siemens series (5SL vs 5SJ4). While both are 1-pole MCBs, the 5SJ4 series has different breaking capacity and physical dimensions. The 5SJ4116-6HG40 will not drop into a panel specified around 5SL4363-7 without verifying the mounting footprint and terminal arrangement — the 5SL series uses a different tunnel terminal design and may have a different DIN-rail clip. Always compare the specific order codes before substituting.

What are the key dimensions — depth and width?

Depth is 70 mm, width is 18 mm (1 modular unit), height is 90 mm. Installation depth is also 70 mm.

What compliance documentation does this brand provide?

As a current Siemens SENTRON product, the 5SJ4116-6HG40 is covered by the standard manufacturer documentation including RoHS, REACH, and IEC/EN 60898-1 compliance. Specific certificates (UL, CSA) should be confirmed against the exact order code with the supplier, as regional variants exist.
