Its interrupting capacity hits 330 kA at 240 V AC and 242 kA at 415 V AC — figures that place it squarely in high-fault panels where upstream transformers or large motor drives can dump serious energy into a bolted fault. The ETU320 trip unit gives you adjustable N-conductor protection (OFF, 50%, 100%), which matters when you're running a 4-wire distribution and need to coordinate neutral protection with the phase legs. At 140 mm wide, 181 mm tall, and 86 mm deep, this breaker occupies a standard MCCB footprint in the SENTRON 3VA family — it bolts into a panel via the rear mounting plate or a plug-in base, not a DIN rail. The breaker carries its full 250 A from 40 °C up to 50 °C ambient; above that it derates linearly to 213 A at 70 °C ambient, which is also the maximum operating temperature.","metaTitle":"Siemens 3VA2225-7HL42-0AA0 SENTRON MCCB, 250 A, 4-Pole, ETU3","metaDescription":"Siemens SENTRON 3VA2225-7HL42-0AA0 molded case circuit breaker, 250 A rated, 4-pole, ETU320 trip unit.
