Mitsubishi LSC-300-PCB High-Capacity Magnetic Contactor – LSC Series
When a magnetic contactor fails on the production floor, the consequences are immediate and costly: motors lose control, production lines halt, and safety interlocks may be compromised. In high-demand industrial environments — from steel mills to large HVAC systems — the reliability of every switching component is non-negotiable. The Mitsubishi LSC-300-PCB is engineered precisely for these critical moments, delivering robust, high-capacity motor switching performance that keeps your operations running without interruption.
Within Mitsubishi Electric’s renowned LSC Series, the LSC-300-PCB occupies the heavy-duty tier, designed for large AC motor loads requiring dependable contactor performance at scale. Mitsubishi Electric’s magnetic contactors are trusted across global industrial automation markets — from automotive assembly plants in Japan and Germany to petrochemical facilities in the Middle East — making the LSC-300-PCB a globally recognized standard for high-current motor control applications.
