Item # 545KXX-240VDC, 545 Series - Screw Terminal Latching Contactors
The 545 series is a three or four pole, double make, normally open, dual coil mechanical latch contactor rated up to 7.5 HP. It will hold its last energized position
indefinitely without requiring any power itself. Contacts change state when the appropriate coil is energized. This makes the 545 series especially well suited to battery
driven devices, and to any application where power consumption or coil heating must be minimized..
For Additional Configuration please contact the manufacturer.
