Its adjustable thermal-magnetic trip unit covers a setting range from 375 A to 2 500 A (the frame maximum), so it fits distribution panels where the load is well below the frame's ultimate capability — you set the trip to match the downstream conductor, not the breaker's full rating. ## Breaking capacity by voltage — where this MCCB fits Rated interrupting capacity drops as system voltage rises: 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V. For a 480 V panel (common in North American industrial) the 220 kA rating gives generous headroom above typical available fault currents; at 690 V the 52.5 kA still covers most European 690 V distribution. ## Thermal derating — continuous current across ambient temperature At 55 °C it derates to 241 A, at 60 °C to 232 A, at 65 °C to 222 A, and at 70 °C to 213 A. For a panel that runs warm — say 55 °C inside the enclosure — you still get 241 A continuous, which is only a 3.6 % drop from the nameplate. Mounts on a DIN rail or panel-mount plate: 105 mm wide (4.13 in), 181 mm tall (7.13 in), 86 mm deep (3.39 in). The 3-pole footprint is standard for the 250 A frame size — no special cutout needed beyond what a 250 A MCCB normally occupies. Trip indicator is present (mechanical flag on the front), so a quick visual check confirms the breaker tripped on fault rather than being switched off manually.","metaTitle":"Siemens 3VA2225-8HL32-0DH0 SENTRON MCCB, 250 A, 330 kA at 41","metaDescription":"Siemens 3VA2225-8HL32-0DH0 SENTRON molded case circuit breaker, 250 A continuous, 330 kA breaking at 415 V. 3-pole, line protection, undervoltage release.
