Thermal derating is flat to 200 A up through 50 °C; above that it steps down to 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. ## Auxiliary wiring and internal accessories That means you get remote tripping capability and two sets of dry contacts for status feedback plus one dedicated alarm contact that changes state only when the breaker trips on fault — useful for a PLC input that logs the event separately from a manual open.","metaTitle":"Siemens 3VA1220-5EF32-0JH0 SENTRON MCCB, 200 A, 3-Pole, 121","metaDescription":"Siemens 3VA1220-5EF32-0JH0 SENTRON molded case circuit breaker, 200 A rated at 40 °C, 3-pole, 121 kA interrupting at 415 V.
