The ETU320 trip unit provides LI protection (long-time and instantaneous) with adjustable overload pickup from 160 A to 400 A and instantaneous pickup from 1.5 to 10 times In, so you can tune coordination with downstream breakers without swapping trip units. The adjustable N-conductor protection (OFF, 50%, 100% of phase pickup) lets you protect the neutral on a 4-wire system or leave it unprotected on a 3-wire delta — a detail that matters when the panel feeds mixed loads. The two auxiliary switches and one trip-alarm switch are wired in, so you get remote status and alarm feedback without adding external relays.","metaTitle":"Siemens 3VA2340-6HL42-0AJ0 Circuit Breaker, 400A, 85kA @ 415","metaDescription":"Siemens 3VA2340-6HL42-0AJ0 IEC frame 400 circuit breaker, 85kA breaking capacity at 415V, 4-pole, ETU320 LI trip unit, In=400A.
