Product details

The Siemens SENTRON 5SU9353-1KK10 is a 2-pole RCBO — a residual-current-operated circuit breaker that combines overcurrent protection (C-curve, 10 A) with 30 mA AC residual current detection in a single 36 mm wide module.

Mounting position any, supply feed from top or bottom. Neutral conductor is switched internally, so no separate neutral bar needed for the protected circuit.

Rated 10 A at 30 °C ambient, C-curve. Surge current withstand 1 kA (8/20 µs) and insulation voltage 264 V. Temperature range -40 to 75 °C covers unheated service areas and outdoor enclosures within the IP20 limit.

Frequently asked questions

Who supplies 5SU9353-1KK10 and how is it quoted for volume purchases?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is 5SU9353-1KK10's listed depth (77 mm) on this component line?

The total depth is 77 mm; the installation depth (behind the panel face) is 70 mm.

What is 5SU9353-1KK10's listed width (36 mm) on this component line?

Width is 36 mm, which corresponds to 2 modular width units on a standard DIN rail.

Will 5SU9353-1KK10 drop into a panel that was specified around 5SU9304-1KK32 without rewiring?

Both are 2-pole SENTRON RCBOs with the same 36 mm width and DIN-rail footprint, so physical fit is the same. However, the 5SU9304-1KK32 is a 32 A, 30 mA, A-type device; the 5SU9353-1KK10 is 10 A, 30 mA, AC-type, C-curve. The electrical ratings differ — verify the load and residual current type before substitution.

What compliance documentation does this brand provide for 5SU9353-1KK10 (RoHS, REACH, UL, IEC)?

The part is designed to EN 60898 and carries IEC 81346-2 and DIN EN 61346-2 function designations. It is halogen-free and silicon-free. For specific RoHS/REACH/UL declarations, the manufacturer's compliance documentation is available on request.
