Product details

Part identity and ratings

Acceptable in any mounting position, which simplifies layout in tight enclosures where vertical or horizontal orientation is constrained.

Electrical and environmental limits

Rated for AC/DC operation: on DC circuits the maximum voltage is 60 V, making it suitable for control-voltage distribution in panels with 24 VDC or 48 VDC supplies. Insulation voltage rated at 440 V AC, with multi-phase operation up to 440 V AC — adequate for 230/400 V three-phase systems where the breaker protects a single-phase branch. Storage temperature range from -40 °C to +75 °C covers most unheated warehouses and transport conditions; the operating ambient is limited to 45 °C (per the 5SJ6 family spec), with periodic humidity up to 95% at 55 °C. Vibration resistance tested to IEC 60068-2-6 at 50 m/s² (25–150 Hz) and 60 m/s² (10–150 Hz), so it holds up in panels mounted on pumps, compressors, or conveyor drives.

Frequently asked questions

Where can I buy the 5SJ6516-7 and get a price?

The 5SJ6516-7 is sourced to order through the authorized Siemens distribution channel. Submit an RFQ for current pricing and availability — confirmed at quote time.

What is the difference between the 5SJ6516-7 and the 5SJ6216-6?

The 5SJ6516-7 uses a C-curve (5–10× In magnetic trip) while the 5SJ6216-6 uses a B-curve (3–5× In). Both are 16 A, 1P+N, 6 kA breakers in the same 5SJ6 family with identical 70 mm depth and DIN-rail footprint. Choose the C-curve when the load has moderate inrush; the B-curve for resistive or electronic loads with low start-up current.

Will the 5SJ6516-7 drop into a panel specified for the 5SJ6220-6?

Yes — both are 1P+N, 2 width units, 70 mm depth, same DIN-rail mounting. The 5SJ6516-7 is 16 A C-curve; the 5SJ6220-6 is 20 A B-curve. No rewiring needed if the panel bus and load current are compatible with 16 A.

What compliance documentation is available for the 5SJ6516-7?

The 5SJ6516-7 is halogen-free and silicon-free, and carries approvals per EN 60898 and IEC 60947-2. Standard Siemens declarations (CE, UKCA, RoHS, REACH) are available on request.
