Its C tripping characteristic means it holds through moderate inrush (5–10× rated current) before tripping magnetically — a fit for motor-starter and transformer-fed loads where a B-curve would nuisance-trip on startup. Breaking capacity is dual-rated: 6 kA per IEC/EN 60898-1 for residential / light commercial, and 15 kA per IEC 60947-2 / UL1077 for industrial panels where higher fault current is expected.
Mounts in any position. The quick-assembly system clips onto the rail without tools — standard for SENTRON 5SY series breakers.
Thermal derating — the real-world rating
The 32 A nameplate holds only up to 35 °C ambient. At 40 °C it derates to 30.72 A; at 50 °C to 29.41 A; at 55 °C to 28.74 A.
