The Siemens SENTRON 5SV9316-1CN32 is an RCBO — a residual-current-operated circuit breaker — combining overcurrent protection and earth-leakage detection in a single 18 mm wide module. The 32 A rating at 30 °C and 6 kA breaking capacity per EN 60898 and IEC 60947-2 mean it clears a bolted fault up to 6 kA without welding its contacts, and the 30 mA trip threshold keeps touch-voltage exposure under the 50 V safety limit in TN systems.
The 77 mm depth plus 70 mm installation depth means it clears a 70 mm deep enclosure without the conductors forcing the door. Supply can enter from top or bottom — no need to flip the busbar orientation.
Thermal derating and ambient range
At 40 °C it derates to 30.4 A, at 45 °C to 29.44 A, at 50 °C to 28.8 A, and at 55 °C to 27.84 A.
