For a 480 V delta panel, the relevant figure is the 242 kA at 440 V, which covers most industrial service-entrance requirements. The TM220 overcurrent release provides thermal-magnetic protection: the thermal element handles overloads up to the 320 A frame, and the magnetic element responds to short-circuit currents. Rated current holds at 320 A from 40 °C through 50 °C (–), then derates linearly to 292 A at 70 °C. The 80.1 W maximum power loss should be factored into enclosure thermal calculations, especially in a sealed panel.","metaTitle":"Siemens 3VA1332-7EE32-0AA0 SENTRON MCCB, 320A, 440kA at 240V","metaDescription":"Siemens 3VA1332-7EE32-0AA0 SENTRON molded case circuit breaker, 3-pole, 320A rated at 40°C, 440kA breaking capacity at 240V AC.
