Breaking capacity hits 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 7.5 kA at 690 V. Ground-fault monitoring uses summation current formation on L+N, so it catches leakage without an external CT. Communication function is built in — this breaker talks to the control system, so you get remote trip indication and load monitoring without an add-on module. Mechanical endurance is rated at 20 000 operations, and maximum power loss is 37.5 W — the heat it dumps into the panel is manageable, but factor it into your thermal budget if the enclosure is sealed. Footprint is 248 mm high, 184 mm wide, 110 mm deep — a 4-pole frame that bolts into a standard MCCB mounting plate. If you're replacing a 5SQ2670-2YA63 or similar legacy frame, the 3VA2325-7KQ42-0AA0 is the functional successor — same 250 A, 4-pole class, but with the ETU860 electronic trip and communication built in. The mounting hole pattern and bus-bar spacing are standard for this frame size, but verify the lug kit compatibility if your panel uses an older termination style.","metaTitle":"Siemens 3VA2325-7KQ42-0AA0 SENTRON MCCB, 250 A, 4-Pole, 330","metaDescription":"Siemens 3VA2325-7KQ42-0AA0 SENTRON molded case circuit breaker, 250 A rated, 4-pole, 330 kA at 240 V.
