It's the main disconnect and fault protection for a feeder or large motor branch in a 400 V panel — the kind of breaker you spec when you need adjustable thermal-magnetic or electronic curve shaping and a high interrupting rating. ## Breaking capacity — what the voltage columns mean for your fault duty This breaker carries 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V. At 415 V, 121 kA covers most industrial service-entrance and large sub-feed applications without series-rating gymnastics. Rated 400 A from 40 °C through 50 °C, then it steps down: 384 A at 55 °C, 376 A at 60 °C, 368 A at 65 °C, 360 A at 70 °C. Size your load and enclosure ventilation accordingly. ## What's inside — trip unit and aux contacts The basic switch is order code 3VA2440-5HL32-0AA0; the integrated auxiliary trip is 3VA9608-0BB24. ## Panel fit — dimensions and environment At 248 mm high, 138 mm wide, 110 mm deep, this is a standard 3VA2 frame — it bolts into the same footprint as other 3VA2 breakers. Max power loss is 63.5 W, so factor that into your enclosure thermal budget if you're packing multiple breakers in a closed cabinet.","metaTitle":"Siemens 3VA2440-5HL32-0AD0 SENTRON MCCB, 400 A, 3-pole, ETU3","metaDescription":"Siemens SENTRON 3VA2440-5HL32-0AD0 molded case circuit breaker, 400 A rated, 3-pole, ETU320 release, 187 kA at 240 V.
