Trombetta, in partnership with MurCal, is a global leader in designing and manufacturing industrial DC contactors. These versatile and durable devices are essential for controlling electrical power in motors and other systems across numerous industries. Built to handle high currents and tough conditions, Trombetta DC contactors are trusted by professionals worldwide for their reliability and adaptability.
What is a DC Contactor?
A DC contactor is an electrical switching device designed to handle high current levels. It works by applying voltage to a coil, creating a magnetic field that moves the contacts into the closed position, completing the circuit. When the voltage is removed, the contacts open back up, disconnecting the circuit. This design allows DC contactors to manage high inrush currents while ensuring safe and efficient operation.
How Do DC Contactors Work?
DC contactors are used to make or break an electrical power circuit, such as those found in motors. The contactor’s low-voltage coil generates a magnetic field that moves its armature, closing the circuit. When the current stops flowing, the coil de-energizes, opening the circuit again. This mechanism protects sensitive components like programmable logic controllers (PLCs) from power surges that could cause damage.
