Function

The 3RT1965-5NB32 functions as the heart of the compatible contactor. It converts the low-level 21-27.3V AC/DC control signal (typically from a PLC via the 24V DC input interface) into the magnetic force required to mechanically close or open the main power contacts of the 3RT106 or 3RT146 contactor. The changeover capability allows for quick and efficient replacement or system modification.
