How does this overload relay work?
This component has a thermal overload release, or bimetallic plate, which opens the contacts to disrupt the flow of electricity when excess current passes over it. This process disconnects the power to prevent damage and improve safety.
What termination method does the relay use?
The device has screw terminals, so you get a secure connection that won't wobble loose under vibration.
