INSTALLATION INSTRUCTIONS
Please read all installation instructions before using DRA Series 3 Phase / Reversing Contactors.
Install the contactor on the DIN rail as shown in fig. 1. Vertical
mounting operation is recommended.
Wire the contactor to the input control side following the
corresponding wiring diagram (fig. 3 or fig. 4). AWG #24 minimum,
AWG #12 maximum (0.2-3.3 mm2), choose wire gauge according to
load current. Maximum recommended terminal screw torque input To remove from
DIN rail
4.3 in-lbs (0.5 Nm).
Wire the contactor to the AC Line side (L1, L2 & L3) and to the Load
side (T1, T2 & T3). AWG #24 minimum, AWG #10 maximum (0.3-5.3
mm2), choose wire gauge according to load current. Maximum
To install on DIN rail
recommended terminal screw torque output 12 in-lbs (1.37 Nm).
If multiple units are installed be sure to follow derating curve (fig. 2). fig. 1 Mounting/Dismounting contactor on DIN rail.
