The Siemens 3VA4180-6ED34-3AA0 is a 3-pole UL Frame 125 circuit breaker with a 65 kA interrupting capacity at 480 V — class H, meaning it safely clears high-fault currents in a 480 V distribution panel without upstream devices needing to trip. The TM210 thermal-magnetic trip unit is fixed at 80 A overload protection (Ir=80 A) with a short-circuit pickup of 10× In (Ii=800 A). That fixed overload setting means it's sized for a specific 80 A feeder or load; you're not adjusting it in the field. The FTFM (Fixed Thermal, Fixed Magnetic) designation confirms both elements are non-adjustable — install it, torque the lugs, and it's set. This breaker sits in the 3VA4 family, a compact molded-case line designed for panelboard and switchboard integration. The 3-pole configuration handles three-phase circuits typical for motor control centers, lighting panels, or feeder distribution in commercial and industrial buildings.
