The interrupting capacity at 240 V is 330 kA; at 415 V it's 242 kA, and at 690 V it holds at 52.5 kA. This is the motor protection version, meaning the ETU350M electronic trip unit is configured for motor loads — it includes phase failure detection, so it will trip on a lost phase before the motor burns. That's a lot of signaling for a single breaker — useful when you need remote status on a motor feeder without adding separate contact blocks. ## Integration — panel fit and thermal management The 138 mm width for a 3-pole 250 A frame is tight for the rating; plan for side-by-side mounting with the manufacturer's recommended spacing to avoid mutual heating. Maximum power dissipation is 37.5 W, which is moderate for this class — the enclosure ventilation needs to move that heat, especially if the breaker is enclosed in a non-ventilated panel. The continuous current rating holds at 250 A from 40 °C through 50 °C, then steps down: 240 A at 55 °C, 235 A at 60 °C, 230 A at 65 °C, and 225 A at 70 °C.","metaTitle":"Siemens 3VA2325-7MN32-0KL0 SENTRON MCCB, 250 A, 330 kA at 24","metaDescription":"Siemens 3VA2325-7MN32-0KL0 SENTRON molded case circuit breaker, 250 A rated, 330 kA breaking at 240 V.
