ОПИСАНИЕ ПРОДУКТА
SCHNEIDER ELECTRIC LC2D12BD - Reversing Contactor
The SCHNEIDER ELECTRIC LC2D12BD is an electromechanical reversing contactor from the TeSys D series, engineered for robust control of three-phase AC motors in industrial environments. This unit facilitates forward and reverse operation of motors up to 5.5 kW at 400V, integrating a 24VDC control coil for precise switching. It is designed for applications requiring frequent operational cycling, such as material handling systems, pumping stations, and general machinery control.
