What this breaker is and what the ratings mean for your panel
The Siemens 3VA4112-6ED24-3AA0 is a 2-pole UL Frame 125 molded-case circuit breaker from the 3VA4 series, rated for line protection with a TM210 thermal-magnetic trip unit. The headline number here is the 65 kA interrupting capacity at 480 V — that means this breaker can safely clear a fault current up to 65,000 A without welding its contacts or rupturing the case. For a 480 V distribution panel, that puts you in H (high) breaking capacity class, which is what you need when the available fault current at the panelboard exceeds 25 or 50 kA. The TM210 trip gives you fixed overload protection at Ir = 125 A (no adjustment dial), and the instantaneous short-circuit pickup is fixed at Ii = 10 × In (1250 A). That's a standard motor-circuit or feeder breaker setup — the fixed Ir means you order it for exactly 125 A and don't touch it in the field.
