What's in the box — 3VA1125-5GD42-0AA0-ZD00
This is a Siemens 3VA1 IEC frame 160 molded case circuit breaker, breaking capacity class M. It's rated Icu=55kA @ 415V, 4-pole, with a line protection TM210 trip unit — fixed thermal-magnetic, no adjustment. Overload protection Ir is fixed at 25A; short-circuit protection Ii is fixed at 12.8 x In (320A). It includes 100% N conductor protection and a nut keeper kit. The OEM destination is DC Power in China — so if you're pulling this off a plant-closure pallet, that's the original build target.
