SCHNEIDER ELECTRIC 31349 - TeSys D 3-Pole Contactor
The SCHNEIDER ELECTRIC 31349 is an electromechanical TeSys D series contactor designed for industrial motor control and resistive load switching applications. This device facilitates the switching of power circuits up to 32A (AC-3) and 50A (AC-1) with a 24V DC control coil, integrating seamlessly into control panels for machinery, HVAC systems, and pumping stations requiring robust power circuit management. It provides reliable switching for three-phase AC motors and general power distribution.
