At 690 V the capacity drops to 52.5 kA, still sufficient for most 690 V industrial loads. The ETU320 release allows adjustable long-time, short-time, and instantaneous pickup, so you can coordinate with downstream breakers for selective tripping — a key requirement when protecting a bus feeding multiple motor starters. ## Thermal Derating and Ambient Range Rated 400 A from 40 °C to 50 °C without derating; at 55 °C it holds 384 A, at 60 °C 376 A, at 65 °C 368 A, and at 70 °C 360 A. In a sealed panel with multiple breakers, account for the internal temperature rise — the derating curve lets you size the breaker to the actual load without oversizing. The UVR is wired separately from the main power circuit — typical for emergency-stop or undervoltage protection schemes. No communication function, phase failure detection, or ground fault monitoring on this variant; those are available on other 3VA options if needed.","metaTitle":"Siemens 3VA2440-7HL32-0CC0 SENTRON MCCB, 400 A, 3-Pole, Unde","metaDescription":"Siemens 3VA2440-7HL32-0CC0 SENTRON molded case circuit breaker, 400 A rated continuous current, 3-pole, ETU320 release, 330 kA at 240 V.
