The Siemens 3VA1110-6EE32-0AA0-ZD00 is a 3-pole IEC frame 160 molded-case circuit breaker in breaking capacity class H, rated Icu=70kA at 415 V. The thermal-magnetic TM220 trip unit gives overload protection adjustable Ir=70 A...100 A and fixed short-circuit protection Ii=10 x In, so it's sized for a 100 A feeder or a motor branch circuit where the inrush won't nuisance-trip.
Panel Integration
The nut keeper kit included with this variant secures the breaker for DC Power OEM builds in China — that kit keeps the line-side lugs from loosening under vibration in a transportable or vehicle-mounted cabinet. Verify the gland plate clearance for the 3-pole width before laying out the backpanel.
