The ETU330 electronic trip unit gives you LIG protection: long-time (L) with Ir adjustable 100–250 A, short-time (I) with Ii adjustable 1.5–10 x In, and ground-fault (G) with Ig adjustable 0.2–1 x In and a selectable ground-fault time delay tg of 0.1 or 0.3 s. The undervoltage release is already installed, so the only wiring step is connecting the 208–230 V AC control supply to the release terminals. The ETU330 is a self-powered electronic trip unit; no auxiliary control power needed for the protection functions. Ground-fault sensing uses a residual-current transformer built into the breaker — no external CT or relay required.","metaTitle":"Siemens 3VA2225-5HM32-0DA0 3VA2 IEC Frame 250, 55kA @ 415V","metaDescription":"Siemens 3VA2225-5HM32-0DA0 circuit breaker, 3VA2 IEC frame 250, breaking capacity class M, Icu=55kA @ 415V, 3-pole, ETU330 LIG protection, In=250A.
