AUTOMATIC CIRCUIT BREAKER CLASS S2 22-32A is, most likely, a motor protection circuit breaker, in construction size S2, with current adjustment range of 22 to 32 A. In the data sheets found online, this wording appears particularly on Siemens SIRIUS 3RV2 models, where “S2” indicates the constructive size of the device and 22-32 A the regulation range of the thermal trip.
