The Siemens 3VA1220-5EF32-0BE0 is a 3-pole IEC frame 250 molded-case circuit breaker rated at In=200A with a TM240 thermal-magnetic trip unit.
Trip settings and accessory integration
Overload protection Ir is adjustable from 140A to 200A via the TM240 dial, and short-circuit pickup Ii is set at 5 to 10 times In — so for a 200A breaker, instantaneous trip can be anywhere from 1000A to 2000A. That range lets you coordinate with downstream branch breakers without nuisance tripping on motor inrush. All accessories mount internally on the 3VA1 frame — no external wiring modules needed.
