The Siemens 3VA4160-4ED14-3AA0 is a 1-pole circuit breaker from the 3VA4 series, built on a UL Frame 125 platform. It carries a 25 kA interrupting rating at 277 V (breaking capacity class S), with a fixed thermal-magnetic trip unit (TM210) set at 60 A for overload (Ir=60 A) and a short-circuit pickup of 10× In (Ii=10 x In). This is a line-protection breaker — sized for branch-circuit duty in a UL 489 panelboard or industrial control panel, not for motor-circuit or feeder coordination.
