Square D TeSys D RC Transient Suppressor
The Square D LAD4RCU is an RC transient suppressor module designed for use with TeSys D series contactors (LC1D09 through LC1D38). Rated for 110 to 250 VAC, this suppressor module mounts directly on the right side of the contactor in its dedicated cavity, protecting control circuits from voltage transients and suppressing coil noise.
