Schneider Electric LC1D18BDLRD21 Power Contactor

Schneider Electric LC1D18BDLRD21 Power Contactor combines a three-pole LC1D18 magnetic contactor with an LRD21 thermal overload relay to provide motor switching and overload protection for three-phase motors, a configuration commonly installed in motor control centers, conveyors, pumps, compressors, and electrical control panels. It is rated for 18 A (AC-3) and can drive motors up to 7.5 kW at 400/415 VAC (AC-3), with an overload adjustment range of 12–18 A and a Class 10A thermal overload. The LRD21 overload relay includes 1 normally open and 1 normally closed auxiliary contact, supports rated voltage up to 690 VAC, and has Ui rated at 690 VAC, enabling safe integration into 690 VAC control circuits. Mounting is flexible: direct mounting beneath the LC1D18 or DIN rail/panel mounting with accessories, using screw clamp terminals; it is compatible with LC1D18, LC1D25, LC1D32, and LC1D38 contactors and complies with IEC 60947-4-1, UL, and CSA.
