Is a magnetic overload affected by changes in temperature?

A magnetic overload device operates primarily based on the magnetic field generated by electrical current flowing through a conductor. The fundamental working principle derives from electromagnetic induction, where the magnetic field strength is proportional to the current rather than temperature fluctuations.

Temperature changes may impact the physical characteristics of materials, such as conductivity or resistance; however, the designed function of a magnetic overload device remains focused on current levels. Therefore, while there can be incidental effects related to general performance characteristics of electrical equipment due to temperature, the magnetic overload mechanism itself does not rely on temperature variations to operate.

This understanding illustrates that such devices are predominantly current-sensitive, functioning effectively within their designed parameters irrespective of ambient temperature changes.
