Siemens SIRIUS Conventional Operating Mechanism AC/DC Coil 220–240 V, S10 Size - 3RT1965-5AP31-8K

Product Description

The Siemens 3RT1965-5AP318K is a SIRIUS conventional operating mechanism with a universal AC/DC coil, designed for compatible Siemens SIRIUS power contactors. It is intended for S10-size contactor applications and operates with a 220–240 V AC/DC control supply. The AC operating frequency is 40–60 Hz. Siemens documentation for the corresponding 3RT1965-5AP31 operating mechanism confirms AC/DC operation at 220–240 V and identifies it for 3RT106/3RT146 contactors.

The 3RT1965-5AP318K is suitable for replacement and maintenance of compatible SIRIUS contactor assemblies used in industrial motor-control panels, electrical control cabinets, machine automation systems, OEM equipment, and factory electrical installations.

Its universal conventional AC/DC coil provides flexibility for control circuits using either AC or DC supply within the specified voltage range. The S10-size construction is designed for compatible Siemens SIRIUS contactor assemblies.
