Product Description
A power contactor is an electrically operated, high-power switch that safely controls heavy electrical loads like motors, lighting, and heating systems by making or breaking connections in a circuit. It functions similarly to a relay but is built to handle significantly higher currents and voltages than standard relays, allowing a low-power control signal to indirectly operate a high-power circuit. Contactors ensure safety by isolating the control system from the high-power load and often include features for overload protection and remote operation.
