With a 240 V AC 50/60 Hz coil and an AC-3 rating of 25 A, the Schneider LC1D25U7 is the TeSys Deca contactor for motors up to 11 kW at 400 V. It carries 1 NO + 1 NC auxiliary contacts as standard. At 220/230 V the AC-3 motor rating is 5.5 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.
