SCHNEIDER ELECTRIC 21128 - Contactor Coil (for TeSys D Series)
This component is a direct current (DC) operating coil, catalog number 21128, specifically engineered for integration into SCHNEIDER ELECTRIC TeSys D series contactors. It generates the electromagnetic force necessary to actuate the main power contacts of the host contactor, enabling remote control and switching of industrial motor loads and resistive circuits. This coil is fundamental for the operational control and safety functions of the associated TeSys D contactor in various automation applications.
