What are Thermal Overload Relays?

Our Otec Series of Thermal Overload Relays are protection devices that can be combined with our range of Ktec Series Industrial Contactors to provide protection against thermal overloads and phase failures for motors on a main electrical circuit.

We offer a wide range of adjustable Otec thermal overload relays in a variety of sizes with current ratings from 0.1A to 600A. These thermal overload relays complement our wide range of Ktec industrial contactors to meet all switching demands.

Our Otec range of thermal overload relays also include additional features such as selection of automatic or manual reset and a current adjustment range of +/- 23%.
