The IP20 rating applies only when the distribution board is installed with connected conductors. At 40 °C the continuous current drops to 30.08 A; at 45 °C to 29.12 A; at 50 °C to 27.84 A; and at 55 °C to 25.92 A. If the panel runs warm — common in crowded enclosures — the effective capacity is lower than the label. Factor this into the load schedule.","metaTitle":"Siemens 5SU9304-1KK32 SENTRON RCBO, 32 A, 30 mA, Type C","metaDescription":"Siemens 5SU9304-1KK32 SENTRON RCD-operated circuit breaker, 32 A, 30 mA residual current, Type C, 10 kA breaking capacity.

The 5SU9304-1KK32 is an RCBO that adds 30 mA RCD protection in the same 18 mm footprint. If the panel requires both overcurrent and earth-leakage protection in one device, the 5SU9304-1KK32 is the correct choice; the 5SY4116-7CV would need a separate RCD module."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SU9304-1KK32","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/5SU9304-1KK32 when reusing this data.
