The Siemens SENTRON 5SU1656-0KK32 is a 2-pole (1P+N) residual current circuit breaker with overcurrent protection — an RCBO — rated 32 A at 30 °C with a Type B tripping characteristic.
Current derating and panel fit
Rated current drops from 32 A at 30 °C to 24.64 A at 70 °C — a meaningful derating curve if the panel runs hot. IP20 with the distribution board installed and conductors connected.
Marked as current production. No EOL notice or successor assigned.
