What this reversing contactor assembly delivers
The Siemens 3RA2315-8XB30-1BB4-Z W97 is a factory-assembled reversing contactor assembly rated AC-3e/AC-3 at 7 A, switching 3 kW at 400 V across three poles. The 24 V DC coil makes it a direct fit for PLC-driven or safety-relay-controlled reversing circuits where you need one compact unit with the mechanical and electrical interlock already built in — no risk of both contactors closing simultaneously and shorting the phases.
Where it fits in the panel
This assembly snaps onto a standard DIN rail and connects via screw terminals. The multi-unit packaging ships as a pack of 8.
