The Type A fault current detection handles pulsating DC residual currents, which is what you get from single-phase rectifiers in VFDs, switching power supplies, and LED drivers. It's rated for overvoltage category III, which covers fixed-installation downstream of the utility meter. The energy limiting class is 3, meaning it lets through less fault energy than a class 1 or 2 device, so downstream components see less stress during a short circuit. At 40 °C it derates 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. Power dissipation is 1.5 W, which is modest for a 32 A RCBO. IP20 with conductors connected and distribution board installed — standard for enclosed distribution boards. Touch protection is built in.","metaTitle":"SENTRON 5SU9354-8KK32 RCBO, 32A, Type A, 10kA, 2-module","metaDescription":"SENTRON 5SU9354-8KK32 RCD-operated circuit breaker, 32 A rated, Type A, 10 kA breaking capacity, 2-pole 1P+N, tripping characteristic D.

The difference is rating: the 5SU9354-8KK63 is a 63 A version.
