This contactor is an electromechanical device designed to control the connection and disconnection of high current electrical circuits in 12-volt systems, supporting a nominal current of 100 amps. It reduces installation costs and weight by eliminating the need for extensive cable runs to manual switches through remote switching of auxiliary and high amperage motor loads. Ensures flawless operation throughout the installation's lifespan with a hermetically sealed contactor against dust and moisture intrusion.
