The ETU560 electronic trip unit provides LSIG protection (long-time, short-time, instantaneous, and ground-fault) with an adjustable overload protection range Ir = 160 A to 400 A, short-circuit protection Isd = 0.6 to 10× In, and instantaneous pickup Ii = 1.5 to 10× In. Ground-fault protection is switchable with Ig adjustable from 0.2 to 1× In and time delay tg = 0.05 to 0.8 s. This level of adjustability lets the breaker be fine-tuned for cable protection, motor branch circuits, or transformer feeders without swapping trip units. Neutral conductor protection is adjustable (OFF, up to 100% of In), and the breaker includes a nut keeper kit, an undervoltage release rated 208–230 V AC 50/60 Hz, two auxiliary switches, and one trip alarm switch — all factory-integrated, so no separate accessory ordering for these functions.","metaTitle":"Siemens 3VA2340-6JQ42-0DJ0 Circuit Breaker, 400A, 85kA @ 415","metaDescription":"Siemens 3VA2340-6JQ42-0DJ0 IEC frame 400 circuit breaker, 85kA breaking capacity at 415V, ETU560 LSIG protection, 400A.
