How do I install this overload relay?
The unit has screw-type terminals for quick installation and secure connections.
How does a thermal overload relay work?
Thermal overload relays like this one use a bi-metallic plate to detect excessive current when it passes through the heating element. If there's a risk of overload, the plate twists out of shape and interrupts the power supply.
