Rated 400 V AC (overvoltage category III) and breaking 15 kA per EN 60898 or 50 kA per IEC 60947-2, this MCB handles the fault-current levels typical of a 400 V distribution board. The 50 kA rating under IEC 60947-2 means it's tested for industrial-grade fault interruption, not just residential service. The D tripping characteristic means the magnetic trip operates at 10–20× rated current — about 16–32 A for this 1.6 A unit. That's the right choice for circuits feeding motor starters, solenoid banks, or small transformers where the inrush peak exceeds the 5–10× range of a C-curve breaker. Breaking capacity: 15 kA at 400 V AC per EN 60898 (the residential/light-commercial standard) and 50 kA per IEC 60947-2 (the industrial standard). At 440 V AC with multi-phase operation, the rating holds at the same 50 kA per IEC 60947-2. That covers unheated enclosures in cold climates and hot panel interiors near transformers or drives. The quick-assembly mounting system snaps onto the rail without tools.","metaTitle":"Siemens 5SY7415-8 SENTRON MCB, 4P, D Curve, 1.6 A, 15/50 kA","metaDescription":"Siemens 5SY7415-8 SENTRON miniature circuit breaker, 4-pole, D tripping characteristic, 1.6 A rated current.
