The Schneider Electric LC1D18BL is a TeSys Deca 3-pole contactor rated 18 A in AC-3 at up to 440 V, for motors of 7.5 kW at 380/400 V, with a 24 V DC coil. It carries 1 NO + 1 NC auxiliary contacts as standard. At 220/230 V the AC-3 motor rating is 4 kW.
TeSys D (now TeSys Deca) is probably the most widely installed contactor range in the world, so the LC1D is a standard spare in factories from the Gulf to North Africa. The coil letter code at the end of the reference sets the control voltage.
See our Schneider Electric range for TeSys overload relays and GV2 breakers.
