The Type C tripping characteristic (5–10× In magnetic release) suits motor and lighting loads with moderate inrush; the AC fault-current type detects sinusoidal residual currents. Active in the current Siemens lineup, so factory supply is standard — no last-time-buy pressure. Wire capacity: solid or stranded 0.75–35 mm² — that's a generous terminal for a 32 A device, allowing easy feed-through of larger supply conductors. Mounting position any, which simplifies panel layout. Rated current drops with ambient temperature: 32 A at 30 °C, 30.4 A at 40 °C, 28.8 A at 50 °C, down to 24.64 A at 70 °C. If the panel runs hot (e.g., enclosed switchgear or adjacent heat sources), use the 50 °C or 60 °C column for your load calculation. Operating ambient range -25 to +55 °C; storage -40 to +75 °C. Maximum power dissipation 11.4 W — relevant for thermal budgeting in a multi-device enclosure. The 5SU1 design is the standard Siemens RCBO platform for the European and export markets.","metaTitle":"Siemens 5SU1354-1LB32 SENTRON RCBO, 32 A, 10 kA, Type C","metaDescription":"Siemens 5SU1354-1LB32 SENTRON RCBO, 2-pole 1P+N, 32 A rated, 10 kA breaking capacity, Type C characteristic.
