Breaking capacity is 10 kA per EN 60898 and 20 kA per IEC 60947-2, giving the part headroom for high-fault installations — the IEC 60947-2 rating is the one to use when coordinating with upstream devices in an industrial panel. ## Thermal derating — the real-world current rating Above that, derate linearly: 9.5 A at 40 °C, 9 A at 50 °C, 8.5 A at 60 °C, and 7.7 A at 70 °C. In a warm enclosure (50 °C+), the effective continuous current is closer to 9 A — factor that into the load calculation. Snaps onto DIN rail, 2 MW wide (36 mm). ## Construction and compliance Energy limitation class 3 — meaning it limits let-through energy to a low level during a fault, protecting downstream equipment.","metaTitle":"Siemens 5SU1354-6LB10 SENTRON RCBO, 2-pole 10A Type A, 10kA","metaDescription":"Siemens 5SU1354-6LB10 SENTRON RCBO, 2-pole 10A Type A, 10kA (EN 60898) / 20kA (IEC 60947-2), B-curve.
