What Are Sealed DC Contactors?
A sealed DC contactor is an electromechanical switch used to control the flow of electricity in a DC circuit. The “sealed” feature refers to its design, which prevents contaminants such as dust, dirt, and moisture from entering and damaging the internal components. This feature makes sealed DC contactors ideal for use in harsh environments where exposure to external elements is a concern.
These contactors consist of a coil, a set of contacts, and an actuator. When current flows through the coil, it creates a magnetic field that moves the actuator, opening or closing the contacts to either connect or disconnect the circuit. Sealed DC contactors are designed to handle high currents and voltages, making them indispensable in systems that require reliable switching and control, such as electric vehicles, power distribution systems, and industrial automation.
