SCHNEIDER ELECTRIC 31339 - TeSys D Contactor
This SCHNEIDER ELECTRIC TeSys D contactor, designated 31339, is a three-pole electromechanical switching device engineered for reliable control of asynchronous motors and resistive loads up to 9A AC-3. It integrates a 24V DC control coil and features one normally open and one normally closed auxiliary contact for status indication and interlocking within industrial control circuits. This component is essential for motor starters, power distribution panels, and automation systems requiring robust load switching capabilities.
