Rated 25 A at 30 °C with a 30 mA residual-current trip, Type A, characteristic C, and a 10 kA breaking capacity per EN 60898 and IEC 60947-2. This is a 1P+N unit (switched phase, solid neutral), designed for instantaneous fault clearing. The 25 A rating at 30 °C is the headline current; derate to 23.5 A at 40 °C, 22.75 A at 45 °C, 21.75 A at 50 °C, and 20.25 A at 55 °C. Mounting position any, supply feed from top or bottom. IP20 with conductors connected and panel closed, so it's for indoor, dry, pollution-degree-2 environments (normal residential or commercial panels). Overvoltage category III means it's rated for fixed-installation downstream of the service entrance. Marked as current production. This is not an NRND or obsolete line — the SENTRON RCBO family remains active in Siemens' catalog. No official successor exists because none is needed.","metaTitle":"Siemens 5SU9354-7KK25 SENTRON RCBO, 25 A, 30 mA, Type A, C","metaDescription":"Siemens 5SU9354-7KK25 SENTRON RCD-operated circuit breaker. 25 A rated, 30 mA residual current, Type A, C characteristic, 10 kA breaking capacity.
