Product details

The 6 A rating at 30 °C is the nominal current; at 40 °C it derates to 5.64 A, at 50 °C to 5.22 A, and at 55 °C to 4.86 A. Insulation voltage is rated 264 V, surge voltage resistance 4 kV, overvoltage category III — suitable for fixed-installation mains distribution. The 18 mm width (1 modular unit) saves rail space compared to a separate MCB+RCCD pair.

Snap-on DIN rail mount, any position. IP20 with distribution board installed and conductors connected; not rated for wet or dusty environments without an outer enclosure. Supply can enter from top or bottom. Touch protection is provided on the terminals.

Frequently asked questions

What is the closest functional second-source for 5SU9304-1KK06?

The 5SY6006-7 is a 2-pole RCBO with similar ratings (6 A, C-curve, 30 mA) but from a different SENTRON sub-series. The 5SU9304-1KK06 is halogen-free and silicon-free; the 5SY6006-7 may not share those material properties. Check the specific material declarations if outgassing is a concern in your panel.

What is the width of 5SU9304-1KK06?

18 mm, which is one modular unit (1 MW) on a DIN rail.

What compliance documentation does Siemens provide for 5SU9304-1KK06?

The part is rated per EN 60898 for breaking capacity (10 kA) and carries overvoltage category III. It is halogen-free and silicon-free. For specific RoHS, REACH, or UL declarations, request the manufacturer's compliance certificate at quote time.

How do I get current pricing and availability for 5SU9304-1KK06?

Submit an RFQ — this part is sourced to order through independent distribution, and availability with current pricing is confirmed at quote time.
