The ETU330 electronic trip unit provides LIG protection: long-time (overload) adjustable from 250 A to 630 A, short-time (instantaneous) from 1.5 to 9× In, and ground-fault pickup from 0.2 to 1× In with a time delay of 0.1 or 0.3 s. The 630 A frame and 55 kA Icu at 415 V place this breaker squarely in main or heavy-feeder duty for 400 V class industrial panels. The ETU330 LIG trip unit covers the three protection curves needed for grounded-wye systems: overload (Ir), short-circuit (Ii), and ground-fault (Ig with adjustable time delay). The undervoltage release (208–230 V AC) drops the breaker when control voltage is lost — common for emergency-stop or safety circuits.","metaTitle":"Siemens 3VA2463-5HM32-0DC0 circuit breaker, 630A, Icu=55kA @","metaDescription":"Siemens 3VA2 IEC frame 630A circuit breaker, line protection ETU330, LIG, Icu=55kA @ 415V, ground-fault, undervoltage release 208-230V AC.
