What this breaker is and what the ratings mean
The Siemens 3VA4111-5ED24-3AA0 is a 2-pole molded case circuit breaker from the 3VA4 UL Frame 125 family, rated for line protection with a fixed TM210 thermal-magnetic trip unit. The In rating is 110 A, with overload protection Ir permanently set at 110 A and short-circuit protection Ii fixed at 10 × In (1100 A). The breaking capacity is 35 kA at 480 V, which is the M (medium) class — meaning it can safely interrupt fault currents up to that level without upstream cascading, suitable for commercial and light industrial distribution panels where fault current stays under 35 kA.
