The Siemens 3VA4111-4ED24-3AA0 is a 2-pole circuit breaker from the 3VA4 UL Frame 125 series, rated for 110 A with a 25 kA interrupting capacity at 480 V. It uses a TM210 thermal-magnetic trip unit with fixed overload protection (Ir = 110 A) and fixed short-circuit protection (Ii = 10 x In). This is a line-protection breaker, not a motor-protection device — the fixed Ir means you cannot dial it down to match a motor FLA.
Compliance and documentation
RoHS compliant since 13-05-19. REACH Article 33 duty to inform applies: lead (CAS 7439-92-1) is present above 0.1% w/w in the product. Export controls are AL: N / ECCN: EAR99 — no special licensing for most destinations.
What the ratings mean for fit
The 25 kA SCCR at 480 V means this breaker safely interrupts faults up to that level without upstream cascading — sized for panelboards and distribution where available fault current is known. The fixed Ir = 110 A means it is a dedicated line-protection breaker for a 110 A feeder or a fixed-load circuit; if you need adjustable overloads for motor starting, look at the 3VA4 with an adjustable TM or electronic trip. The 2-pole configuration suits single-phase or two-pole branch circuits in 480 V systems.
