The 3VA2225-6HL32-0DK0 is a Siemens 3VA2 IEC frame 250 molded-case circuit breaker with a breaking capacity class H rating of Icu=85kA at 415 V AC. The 3-pole, 250 A frame (In=250A) is fitted with an ETU320 LI trip unit offering adjustable overload protection (Ir = 100 A to 250 A) and short-circuit protection (Ii = 1.5 to 10 x In). The LI curve (long-time + instantaneous, no short-time delay) suits it for feeder or distribution duty where you need thermal-magnetic-style coordination but with electronic adjustability.
Deployment context
The 3VA2 frame accepts plug-in or fixed connections; the included undervoltage release and auxiliary switch are wired to the control circuit, not the main power path. In a typical furnace or process line, this breaker sits between the step-down transformer and the motor control center — the 85 kA SCCR at 415 V gives headroom for high-fault industrial grids.
