The Siemens 3VA4180-4ED14-3AA0 is a 1-pole circuit breaker from the 3VA4 series, built on a UL Frame 125 platform. It is rated for a breaking capacity of 25 kA at 277 V, making it suitable for branch-circuit protection in North American 277/480 VAC lighting and distribution panels. The TM210 trip unit provides fixed thermal-magnetic overload protection at Ir = 80 A and short-circuit pickup at Ii = 10 × In (800 A). This is a line-protection device, not a motor-protection breaker — the fixed Ir and high Ii ratio are tuned for feeder and lighting loads, not for starting inrush.
