This is a line-protection version (product version: Line protection), meaning it's set up for feeder and distribution duty — not motor or generator protection — so match it to your downstream cable and bus ratings, not a load's thermal damage curve. Breaking capacity is 330 kA at 240 V AC, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 9 kA at 690 V. ## Lifecycle and sourcing — active, quoted to order The 110 mm depth, 138 mm width, and 248 mm height fit the SENTRON 3VA frame footprint; verify panel cutout and busbar spacing against your existing layout. ## Integration notes — panel fit and wiring Three-pole design with no undervoltage release, no voltage trigger, no ground-fault monitoring, and no communication function — this is a straight thermal-magnetic (electronic) breaker for basic overcurrent protection. If you need shunt trip, UVR, or remote signaling, you'll add external accessories or move to a different 3VA variant. The 5 kA limited-to-1-second rating is a short-time withstand value for selective coordination schemes.","metaTitle":"Siemens 3VA2440-7HL32-0AA0 SENTRON MCCB, 400 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA2440-7HL32-0AA0 molded case circuit breaker, 400 A rated current, 3-pole, ETU320 trip unit, 330 kA at 240 V.
