A power contactor is an electrical device used to turn an electrical circuit on and off. It’s a multi-pole switch, which means it can control numerous power circuits with a single contactor. Regarded as a unique kind of relay, the main difference between the contractors and the relay is that the contactor relay is utilized in applications that require a larger current carrying capacity, whereas the relay is used in conditions that require a lower current carrying capacity.
Applications of Power Contactor Relays
In simple terms, contactor relays are electrically operated switches deployed for effectively controlling electric circuits. There are several types of contactor relays like 4-pole contactors, vacuum contactors, AC contactors, DC contactors, etc that are deployed in a variety of applications like automation circuits, protection circuits, control circuits, and more.
