It carries the ETU330 LIG electronic trip unit combining overload (Ir adjustable 500–1250 A), short-circuit (Ii 1.5–10 x In), neutral protection (adjustable OFF to 100%), and ground-fault protection (Ig 0.2–1 x In, tg 0.1/0.3 s). A left-side shunt trip for 208–277 V AC 50/60 Hz or 220–250 V DC is factory-installed. The 3VA2 frame mounts in a standard panel or switchboard via the included nut keeper kit. The 4-pole form factor and 1250 A frame size mean it occupies a full-width panel cutout; verify busbar and cable lug clearance for the 1250 A rating. The shunt trip is wired left-side, so plan control wiring routing accordingly.","metaTitle":"Siemens 3VA2612-5HM42-0KF0 Circuit Breaker, 1250A, 55kA @ 41","metaDescription":"Siemens 3VA2612-5HM42-0KF0 circuit breaker, IEC frame 1250, breaking capacity class M, Icu=55kA @ 415V, 4-pole, ETU330 LIG, 1250A, adjustable protections, shunt trip.
