Breaking capacity hits 330 kA at 240 V AC, dropping to 242 kA at 415 V and 440 V, then 187 kA at 500 V, and 3.8 kA at 690 V. That 330 kA figure means it handles the full let-through of a large transformer or a utility-grade fault on a 240 V distribution bus — not a rating you see on a 25 A frame every day. Optional motor drive is available as a field-fit accessory, so the breaker can be remotely racked or reset without opening the door. Communication function is not built in — this is a standalone thermal-magnetic replacement, not a smart breaker with Modbus or PROFINET on board.","metaTitle":"Siemens 3VA2125-7HL32-0AA0 SENTRON MCCB, 25A, 330kA at 240V","metaDescription":"Siemens 3VA2125-7HL32-0AA0 SENTRON molded case circuit breaker, 3-pole, 25A rated current, 330kA breaking capacity at 240V AC, ETU320 release.
