Its interrupting rating of 25 kA at 480 V AC puts it in the 'S' (standard) breaking capacity class — enough for most downstream feeder and branch protection in North American 480Y/277 V panels, but not the high-fault 'N' or 'H' classes for transformer secondaries or service entrances. The TM210 trip unit means thermal-magnetic, non-electronic, no adjustable curves; what you see is what you get for coordination studies. This is a made-to-order unit (Product class C), not a stocked shelf item. ## Integration notes Mounts in a standard panel cutout for the 3VA4 frame. The 3-pole unit occupies the same footprint as other 125 A frame breakers in the series. Line and load lugs accept copper or aluminum conductors; torque values per the terminal marking on the breaker. No auxiliary contacts or shunt trips are included in this order code — those are ordered separately and snap into the accessory slots on the left side of the case.","metaTitle":"Siemens 3VA4150-4ED34-3AA0 Circuit Breaker, 50 A, 25 kA @ 48","metaDescription":"Siemens 3VA4150-4ED34-3AA0 circuit breaker, 3VA4 UL Frame 125, 25 kA @ 480 V, 3-pole, TM210, In=50 A, Ir=50 A, Ii=10xIn.
