The 3VA4160-6ED34-3AA0: This is a Siemens 3VA4 molded-case circuit breaker in a UL Frame 125 footprint, rated for 60 A continuous and a 65 kA interrupting capacity at 480 V. For a panel feeding a motor control center or a distribution board, that kind of headroom keeps the upstream transformer and bus from taking a hit during a bolted fault. The overload protection is fixed at 60 A (Ir = 60 A permanently set), and the magnetic short-circuit pickup is at 10 times the rating (Ii = 10 x In), so it trips instantaneously at 600 A. That fixed overload setting means you don't have to fiddle with adjustment dials — it's a straight swap for a 60 A line. The TM210 trip unit is a thermal-magnetic type, so it handles both slow overloads (thermal element) and fast short-circuits (magnetic coil).
RoHS compliance is confirmed since May 2019. It doesn't affect fit or function, but it's a disclosure requirement for EU buyers.
This is a 3-pole breaker in a UL Frame 125 package. The packaging dimensions (472 x 396 x 213 mm) give you a rough idea of the shipping box, but the breaker itself fits a standard 125 A frame cutout. In a typical 480 V distribution panel, it's sized for feeder or branch circuit protection on motor loads, lighting, or general power. The 65 kA SCCR at 480 V means it's suitable for high-fault-capacity installations — think industrial plants with large transformers close to the panel.
