ОПИСАНИЕ ПРОДУКТА
SCHNEIDER ELECTRIC 81686 - TeSys D Contactor
SCHNEIDER ELECTRIC 81686 is a TeSys D series 3-pole contactor engineered for robust industrial motor control and power switching applications. This device features three normally open main power contacts, rated for AC-3 category loads up to 9 Amperes and 4 kilowatts at 400 Volts, controlled by a 24V DC coil. It is designed for reliable operation in demanding industrial environments, facilitating the control of asynchronous motors, resistive loads, and other inductive circuits within automation systems, HVAC, and pumping stations.
