Short-circuit protection is fixed at Ii = 10 × In, and the interrupting capacity reaches Icu = 25 kA at 415 V — enough for most industrial distribution panels where fault levels stay under that threshold. The shunt trip (STL) operates on 110–127 V DC or AC 50/60 Hz, and the breaker ships with two auxiliary switches (HQ) plus a nut keeper kit for secure terminal fastening. Mounts on DIN rail per the 3VA1 frame standard. The nut keeper kit prevents terminal hardware from dropping into live panels during installation — a detail that speeds up panel wiring on the line. The two HQ auxiliary switches provide independent status feedback for remote monitoring or PLC inputs.","metaTitle":"Siemens 3VA1080-3ED42-0JC0 Circuit Breaker, 80A, 25kA @ 415V","metaDescription":"Siemens 3VA1080-3ED42-0JC0 IEC frame 100, 4-pole, 80A fixed TM210, 25kA breaking capacity @ 415V.
