The ETU860 trip unit gives you LSIG protection — long-time (overload), short-time, instantaneous, and ground-fault — with adjustable Ir from 160 A to 400 A, Isd from 0.6 to 10 x In, and Ii from 1.5 to 15 x In. Ground-fault pickup Ig is adjustable from 0.2 to 1 x In with a time delay tg of 0.05 to 0.8 s, which lets you coordinate downstream without nuisance tripping on motor inrush. We source and quote the 3VA2440-5KQ32-0DF0 to order against an RFQ.","metaTitle":"Siemens 3VA2440-5KQ32-0DF0 Circuit Breaker, 400A, 55kA @ 415","metaDescription":"Siemens 3VA2440-5KQ32-0DF0 IEC frame 630 MCCB, 3-pole, ETU860 LSIG, In=400A, Icu=55kA @ 415V.
