Rated 18.5 kW at 400 V (38 A AC-3), the Schneider LC1D38U7 is a TeSys Deca (LC1D) power contactor with 3 NO main poles and a 240 V AC 50/60 Hz operating coil. It carries 1 NO + 1 NC auxiliary contacts as standard. At 220/230 V the AC-3 motor rating is 9 kW.
Contactors of the 38 A frame are among the fastest-moving spares in motor control centres: every start wears the contacts a little, and pump or conveyor feeders can switch hundreds of times per shift.
See our Schneider Electric range for TeSys overload relays and GV2 breakers.

Compatibility and replacement
Pairs with the TeSys LRD thermal overload relay (direct mounting) and the GV2 motor circuit breaker. Add-on blocks such as LADN11 (1NO+1NC) or LADN22 (2NO+2NC) fit on the front. LC1D contactors from older TeSys D production are replaced one-to-one by TeSys Deca of the same reference.
Frequently asked questions
What is the coil voltage?
240 V AC 50/60 Hz, per the Schneider data sheet.
Which overload relay fits?
TeSys LRD relays mount directly under the contactor; choose the setting range that covers the motor rated current.
What motor size can it switch?
Up to 18.5 kW at 380/400 V in AC-3 (38 A).
Can I add auxiliary contacts?
Yes, front-mounted LADN blocks and side-mounted LAD8 blocks can be added.
