The magnetic instantaneous pickup is fixed at Ii = 12 x In, meaning it holds through motor inrush and trips on a hard short. The 3VA4 frame mounts into standard panel-mount cutouts or can be fitted with rotary-handle or motor-operated mechanisms for remote switching. At 35 kA @ 480 V, this breaker is sized for distribution panels in commercial or light industrial settings — think feeder protection, branch circuits feeding motor control centers, or main breakers in a sub-panel where fault current is moderate. The fixed Ir means the load profile must be known at design time; no dialing it up later if the load grows. The packaging dimensions (472 x 396 x 213 mm) give a sense of the shipping box, not the breaker itself — the frame is smaller, but the made-to-order packaging is sized for single-unit shipment.","metaTitle":"Siemens 3VA4125-5ED34-3AA0 Circuit Breaker, 35 kA @ 480 V, 2","metaDescription":"Siemens 3VA4125-5ED34-3AA0 circuit breaker, 3-pole, 35 kA @ 480 V, TM210 trip unit, In=25 A, fixed Ir and Ii.
