The thermal derating curve is flat from 40 °C to 50 °C (full 400 A), then drops to 384 A at 55 °C, 376 A at 60 °C, 368 A at 65 °C, and 360 A at 70 °C; panel builders should check ambient at the breaker location, not the enclosure inlet. The ETU320 electronic trip unit handles the overcurrent protection curve, and the integrated undervoltage release (UVR) — part 3VA9608-0BB24 — allows a remote safety or E-stop circuit to drop the breaker. The maximum power loss is 66 W, so factor that into thermal rise calculations for a sealed enclosure. The 15 000 mechanical endurance cycles suit frequent-switching applications like pump or compressor control.","metaTitle":"Siemens SENTRON 3VA2440-7HL32-0CA0 MCCB, 400 A, 330 kA","metaDescription":"Siemens SENTRON 3VA2440-7HL32-0CA0 molded case circuit breaker, 400 A rated continuous current, 330 kA interrupting at 240 V.
