The Siemens 5SU9356-7KK06 is a SENTRON RCBO — an RCD-operated circuit breaker combining overcurrent and residual-current protection in a single 2-module-wide (36 mm) package.
That dual rating is the key spec for panel builders: the 10 kA figure under 60947-2 gives you SCCR headroom for industrial panels where fault currents can run higher than a residential 6 kA installation. The 4 000 V surge voltage resistance and overvoltage category III mean it's rated for fixed-installation distribution boards, not just final circuits.
At 40 °C it derates to 5.64 A, at 50 °C to 5.22 A, and at 55 °C to 4.86 A. Depth is 77 mm, installation depth 70 mm, and it's IP20 once installed in a distribution board with conductors connected. That's standard for enclosed panel gear; no washdown rating here.
Degree of pollution 2 and overvoltage category III round out the installation class. No UL or CSA listing is stated in the spec record, so verify with your local code authority if you're specifying for a North American panel.
