Overload protection is fixed at 70 A (Ir = 70 A), and the short-circuit magnetic trip is set at 10× In (700 A). ## SCCR and selectivity The 25 kA interrupting rating at 480 V places this breaker in the S-class of the 3VA4 family. In a panel with a 65 kA available fault current, you'd need a current-limiting upstream breaker or fuse to coordinate — this breaker alone won't hold that. Pair it with a properly rated main, and the selectivity tables in the Siemens coordination manual apply. ## Panel integration The TM210 trip unit is non-interchangeable — Ir is fixed at 70 A, so if the load changes, the breaker itself must be replaced. Line and load lugs accept copper or aluminum conductors. The FTFM (fixed thermal, fixed magnetic) trip means no field adjustment of the magnetic pickup; it's locked at 10× In.","metaTitle":"Siemens 3VA4170-4ED34-3AA0 Circuit Breaker, 70 A, 25 kA @ 48","metaDescription":"Siemens 3VA4 UL Frame 125, 3-pole, TM210 trip unit, 70 A fixed, 25 kA @ 480 V.
