The Siemens 3VA2125-7HL32-0AA0 is a 3-pole SENTRON molded case circuit breaker (MCCB) rated for 25 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed as the panel warms up. 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.
