Contactors are commonly used to control current flow in electrical power systems. In particular, the DP4RSA60E20B2 is a type of contactor known as a solid state contactor. This is an electronically controlled device, which uses semiconductor switching for fast and reliable operation.

What is a Contactor?

A contactor is a switch mechanism that opens and closes circuits by breaking or forming electrical contacts. It is similar to a relay, with the distinction being contactors are designed to switch larger currents and have increased contact resistance. Typically, contactors are used in high-voltage circuits for applications including motor control, switching AC lines, and controlling resistive and inductive loads.

Types of Contactors

Contactors are available in both electromechanical and solid state modes. Electromechanical contactors use an electromagnet housed in the contactor body, which controls the movement of the contacts. Solid state contactors, such as the DP4RSA60E20B2, rely on semiconductor switching devices such as relays, transistors, or triacs. These contactors are often compact and require less maintenance than electromechanical contactors.
