For LC2D09 to LC2D38: clip-on mounting on 35 mm DIN rail AM1DP or screw mounting.
Includes mechanical interlock without electrical contacts. Installer to complete wiring for electrically interlocking contactor operating coils by utilizing a N.C. auxiliary contact integrated in the
contactor or optional LADN or LAD8N type auxiliary contact block.
Use voltage codes on page 115 “Voltage Code Table” to complete catalog number.
For reversing contactors with electrical interlocking pre-wired at the factory, add suffix V to the catalog number reflected above. Example: LC2D09
LC2D38 is UL Listed at the same HP rating as the 32 amp device.
