The ETU350 electronic trip unit provides LSI protection: long-time (Ir adjustable 500–1250 A), short-time (Isd adjustable 1.5–10 x Ir), and instantaneous (Ii fixed at 10 x In). This selectivity profile is typical for main or feeder breaker duty where you need time-delayed short-circuit response to let downstream devices clear first. ## Deployment context Mounts in a standard switchboard or panel enclosure on a fixed or draw-out cradle — the frame 1250 footprint is common across the 3VA2 line, so panel cutouts and busbar spacing carry over if you swap variants. The included shunt trip (left-side, 208–277 V AC 50/60 Hz or 220–250 V DC) gives remote tripping capability for emergency-stop circuits or supervisory control. Wire the shunt trip coil separately from the main power path; verify polarity on the DC supply to avoid nuisance operation.","metaTitle":"Siemens 3VA2612-5HN32-0KF0 Circuit Breaker, 1250A, 55kA @ 41","metaDescription":"Siemens 3VA2612-5HN32-0KF0 IEC frame 1250 circuit breaker, 55kA breaking capacity @ 415V, ETU350 LSI protection, 1250A In.
