It's rated 32 A at 30 °C with a C tripping characteristic, meaning it handles moderate inrush from motor starters or capacitor banks without nuisance trips, while the 6 kA breaking capacity per EN 60898 (10 kA per IEC 60947-2) clears line-to-neutral faults up to that level. The Type A fault-current detection catches both sinusoidal AC and pulsating DC residual currents, which covers most modern electronic loads like VFDs and switched-mode power supplies. The unit occupies 2 width units (36 mm) on a DIN rail, with an installation depth of 70 mm and overall depth of 77 mm — fits standard 80 mm-deep enclosures. Terminals accept solid or stranded conductors from 0.75 mm² up to 35 mm², covering everything from 1.5 mm² lighting circuits up to 10 mm² feeder tails. The max power loss of 1.5 W per unit means derating within a multi-pole assembly is minimal — you can pack several of these side by side without cooking the enclosure. Ambient temperature range is -25 to +45 °C, with derating above 30 °C: 30.08 A at 40 °C, 29.12 A at 45 °C, 27.84 A at 50 °C, 25.92 A at 55 °C. The 5SU9 design series is the active SENTRON RCBO line, so you can spec it into new BOMs without worrying about a forced redesign next year. Touch protection is built into the terminals — no exposed live parts when wired correctly. Compared to the standard MCB-only 5SL6563-7BB (a 32 A C-curve without RCD), the 5SU9356-7KP32 adds Type A residual-current protection in the same 2-module footprint. If your panel was laid out around the 5SL6563-7BB, this RCBO drops into the same DIN-rail slot and terminal range — no rewiring needed for the line and load connections, but you gain the ground-fault trip function.","metaTitle":"Siemens 5SU9356-7KP32 SENTRON RCD Circuit Breaker, 32 A, 6 k","metaDescription":"Siemens 5SU9356-7KP32 SENTRON RCD-operated circuit breaker, 32 A rated, 6 kA breaking capacity, Type A, 1P+N, C-curve.
