What this coil fits and why it matters
The 3RT1965-5QF31 is a changeover operating mechanism — a magnet coil assembly — designed for Siemens SIRIUS 3RT106 and 3RT146 contactors in AC (50/60 Hz) or DC operation. It includes an electronic interface with AS-Interface and an RLT (Remote Local Trip) signal, meaning it integrates into a networked control scheme rather than just a standalone coil swap. Rated for 96 V DC and 127 V DC, plus 127 V at both 50 Hz and 60 Hz, with an AC/DC control supply voltage type. That dual-frequency AC rating eliminates confusion when the line frequency varies between plants.
Lifecycle and sourcing reality
Sourced to order against the BOM quantity through independent distribution. Availability and current pricing confirmed at RFQ — no stock-holding claim, but the active status means lead times are generally manageable through the channel.
