PRODUCT DESCRIPTION
SCHNEIDER ELECTRIC 18637 - Contactor
This is a TeSys D series contactor, engineered for reliable motor control and resistive load switching within industrial automation and power distribution systems. It facilitates the switching of AC motors up to 4kW at 400V and general-purpose loads up to 9A, actuated by an integrated AC electromagnetic coil. Primary applications include control of pumps, fans, conveyors, and heating elements in HVAC, material handling, and general machinery.
