Thermal overload relays are protective devices. They are designed to cut power if the motor draws too much current for an extended period of time. To accomplish this, thermal overload relays contain a ...

Bimetallic Thermal Relay Bimetallic thermal relays consist of two strips of different metals. These dissimilar metals are permanently joined. Heating the bimetallic strip causes it to bend because the ...

Relays are electronic devices that accept current or voltage signals in an input circuit as a prompt to switch open or close another circuit or pilot device. In this way, relays are switches that are ...
