Its interrupting capacity hits 30 kA per IEC 60947-2 — enough to handle high-fault industrial feeders without cascading upstream. The D characteristic (10–20× In) means it tolerates the inrush of motor starters and transformer primaries without nuisance tripping. Ambient range spans -40 °C to 75 °C, with derating above 45 °C (31.2 A at 50 °C, 30.37 A at 55 °C). Sealable to prevent unauthorized tampering. Halogen-free and silicon-free construction suits clean-room or sensitive environments.","metaTitle":"Siemens SENTRON 5SY8332-8 MCB, 3P D 32 A, 30 kA, 3 MW","metaDescription":"Siemens SENTRON 5SY8332-8 miniature circuit breaker, 3-pole, D-curve, 32 A AC, 30 kA IEC 60947-2, 3 MW, IP20.
