The trip unit's overload setting (Ir) is adjustable 500 A to 1250 A, and the instantaneous pickup (Ii) is adjustable 1.5 to 10 times In (1875 A to 12,500 A), so you can tune coordination with downstream feeders without swapping the breaker. The description includes an undervoltage release (24 V DC) and provisions for up to four auxiliary switches — these are factory-fitted accessories that connect via the breaker's accessory slot. When wiring the undervoltage release, verify the control voltage source is stable 24 V DC; the release trips the breaker if control power drops, so it's commonly used in emergency-stop chains or safety circuits where loss of control voltage must open the main contacts. ## Selectivity and coordination The ETU320 LI curve, combined with the 85 kA interrupting rating, makes this breaker suitable as a main or feeder breaker in a distribution board where selectivity with downstream MCCBs or fuses is required. The adjustable Ir (500-1250 A) lets you match the cable or busbar ampacity, while the Ii range (1.5-10 x In) allows you to set the instantaneous trip high enough to avoid nuisance tripping on motor inrush or transformer energization. For a site electrical engineer building a coordination study, the trip curve data for the ETU320 is published in Siemens application guides — the breaker's own rating card carries the settings range.","metaTitle":"Siemens 3VA2612-6HL32-0BE0 Circuit Breaker, 1250A ETU320, 85","metaDescription":"Siemens 3VA2612-6HL32-0BE0 IEC frame 1250 air circuit breaker. 85kA breaking capacity @ 415V.
