With a 48 V AC 50/60 Hz coil and an AC-3 rating of 18 A, the Schneider LC1D18E7 is the TeSys Deca contactor for motors up to 7.5 kW at 400 V. It carries 1 NO + 1 NC auxiliary contacts as standard. At 220/230 V the AC-3 motor rating is 4 kW.
In a typical motor starter the LC1D is combined with a TeSys LRD thermal overload relay mounted directly underneath, or with a GV2 motor circuit breaker for fuseless protection.
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
Can I add auxiliary contacts?
Yes, front-mounted LADN blocks and side-mounted LAD8 blocks can be added.
Which overload relay fits?
TeSys LRD relays mount directly under the contactor; choose the setting range that covers the motor rated current.
How long does it last mechanically?
Schneider gives a mechanical durability of 15 Mcycles.
How fast does it close and open?
Per Schneider: 12…22 ms closing; 4…19 ms opening.
