The Siemens 5SY4306-7 is described by Siemens as: Miniature circuit breaker 400 V 10kA, 3-pole, C, 6 A, D=70 mm.
The rated current must match the cable cross-section and the tripping characteristic must suit the load; both are printed on the front of the breaker and listed in the Siemens table below.
