ОПИСАНИЕ ПРОДУКТА
SCHNEIDER ELECTRIC 81282 - TeSys D Contactor
This SCHNEIDER ELECTRIC TeSys D contactor, identified by code 81282, is an electromechanical switching device engineered for robust control of three-phase asynchronous motors and resistive loads in industrial environments. It features a 3-pole configuration, rated for 25A under AC-3 utilization category at 400V, and is actuated by a 24VDC control coil. Designed for integration into motor control centers, HVAC systems, and general power distribution panels, it provides reliable power switching and circuit isolation.
