SIRIUS S6 withdrawable coil — 480 V AC/DC
The 3RT5955-5AR31 is a withdrawable magnet coil from the Siemens SIRIUS family, designed for the S6 modular contactor frame. It's not a standalone contactor — it's the replaceable coil assembly that snaps into the S6 contactor's solenoid cavity.
Lifecycle and sourcing — active production confirmed
Sourced to order against the BOM quantity through independent distribution channels.
What the 480 V AC/DC rating means on the route
The same 480 V DC rating means it also works on DC bus systems common in UPS-backed or battery-supplied control circuits. Being a withdrawable coil, it's meant for the S6 contactor frame where you can swap the coil without pulling the contactor off the DIN rail. That's a real time-saver on a motor control center when a coil burns out and you're trying to keep a pump or conveyor running.
