Short-circuit protection is fixed at Ii = 10 x In (1250 A), which is typical for line protection where you want fast magnetic trip on hard faults but avoid nuisance tripping on motor inrush. Same part, different passport — this unit includes a nut keeper kit configured for a DC Power OEM in China. That means the breaker itself is a standard 3VA1 IEC frame 160 device, but the accessory kit and packaging are tailored for that OEM channel. ## Integration notes for the panel builder The 3-pole footprint fits a 160 A frame cutout; plan for 3 x 70 mm² cable terminations on the line and load side. The TM220 trip unit is field-adjustable without removing the cover — just rotate the dials for Ir and Ii.","metaTitle":"Siemens 3VA1112-3EE32-0AA0-ZD00 Circuit Breaker, 125A, 25kA","metaDescription":"Siemens 3VA1112-3EE32-0AA0-ZD00 IEC frame 160 circuit breaker, 3-pole, 125A, 25kA @ 415V.
