Short-circuit interrupting capacity is the headline number here: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 52.5 kA at 690 V. That puts it in the high-fault tier — you can place this downstream of a large transformer or on a utility service entrance without worrying about cascading failure. The 138 mm width, 248 mm height, and 110 mm depth mean it fits standard SENTRON mounting footprints; no special adapter plate needed for a retrofit into an existing 3VA panel. ## Trip unit, auxiliaries, and what's inside The ETU350M electronic overcurrent release gives you adjustable thermal and magnetic curves plus phase-failure detection — that's the motor-protection core. Power loss tops out at 37.5 W — negligible for panel thermal budgeting but worth noting if you're packing multiple breakers in a sealed enclosure.","metaTitle":"Siemens 3VA2325-7MN32-0KC0 SENTRON MCCB, 250 A, 3-Pole, Moto","metaDescription":"Siemens SENTRON 3VA2325-7MN32-0KC0 molded case circuit breaker, 250 A, 3-pole, motor protection, ETU350M, 330 kA at 240 V.
