Product details

Lead — panel OEM wireman view

Integration — mounting and environment

Mounts in any position via the quick-assembly system (snap-on DIN rail). Operating temperature from -40 °C to 75 °C, with derating: at 40 °C the rated current drops to 3.81 A, at 55 °C to 3.5 A. Humidity derating applies above 55 °C.

Halogen-free and silicon-free construction. Sealable, with combined terminals top and bottom. Touch protection integrated. Energy limitation class 3. The product is designated under IEC 81346-2 and DIN EN 61346-2 as type F.

Frequently asked questions

Where can I buy 5SY6604-7?

The 5SY6604-7 is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the breaking capacity of 5SY6604-7?

It has a 30 kA breaking capacity per IEC 60947-2 and 6 kA per EN 60898.

What is the temperature derating for 5SY6604-7?

At 40 °C the rated current is 3.81 A; at 55 °C it drops to 3.5 A. The full operating range is -40 °C to 75 °C.

Will 5SY6604-7 fit in a panel designed for 5SY6006-7?

Yes — both are 4-pole MCBs in the SENTRON 5SY series with identical 72 mm width (4 MW) and 76 mm depth, so the 5SY6604-7 drops into the same DIN-rail footprint without rewiring.

What compliance documentation is available for 5SY6604-7?

The breaker is halogen-free, silicon-free, and carries touch protection. Compliance documents (RoHS, REACH, UL, IEC) are provided by Siemens for this SENTRON series.
