The Siemens 3RA1210-1CA15-0AV6 is a reversing motor starter in the SIRIUS 3RA family, built on the S00 frame size. It's rated for 480 VAC and 1.8 A, meaning it's sized for small reversing motor loads — think conveyor direction changes or pump valve actuators where you need forward/reverse control in a single panel-mounted package. The reversing contactor pair is mechanically interlocked to prevent simultaneous closure, which is the standard safeguard against phase-to-phase shorts during direction reversal.
The 1.8 A rating at 480 VAC three-phase sizes this starter for a motor drawing that full-load current.
