LC3D18AU7
TeSys Deca , star delta starter , 3 x 3P (3 NO) , 18 A , 240 V AC coil

TeSys D pre-assembled star-delta starter, for motor control applications up to 18.5kW@400V in delta connection. Plate mounted starter, open version, composed of 3 contactors LC1D with 240V 50/60Hz AC coils, 1NC built-in auxiliary contact on star, a time-delay contact block 1-30 sec. For operating rates until 30 starts/hour, maximum starting time 30 sec. Compact assembly (144mm width), screw fixing. Equipped with pre-wired star delta power connections, and mechanical interlock, the use of a thermal overload relay (to be ordered separately) is strongly recommended. Green Premium compliant (RoHS/REACh).
