It provides the mechanical latching function that holds the contactor closed after the coil is energized, then releases it on command or power loss. This dual AC/DC capability simplifies panel wiring — you can feed it from either a control transformer or a DC supply without swapping coils. Because it is current-production, the normal Siemens distribution channel carries it. If your control circuit runs at 240 V AC (common in North American panels), this coil is within range — the 277 V AC rating gives headroom above 240 V. For a 208 V AC control bus, the coil still pulls in reliably since the 277 V rating is the maximum, not the minimum. The electronic operating mechanism includes AS-Interface communication and an RLT (Remote Local Trip) signal. That means this coil can be addressed and monitored on an AS-i network — useful if the contactor sits in a distributed I/O zone where you want feedback on the latching state without running separate sense wires back to the PLC.","metaTitle":"Siemens 3RT1965-5QP31 SIRIUS Magnet Coil, 200-277 V AC/DC","metaDescription":"Siemens SIRIUS 3RT1965-5QP31 changeover operating mechanism for 3RT106/3RT146 contactors.

The coil is rated 277 V at 50/60 Hz, so 240 V AC is well within its operating range. It also accepts 200 V DC, which covers common 24 V DC control buses (24 V is below the 200 V DC rating, so verify your DC bus voltage — this coil is not for standard 24 V DC control)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT1965-5QP31","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RT1965-5QP31 when reusing this data.
