Does the overcurrent device provide overload protection?

The statement that the overcurrent device does not provide overload protection can be understood by exploring the function of overcurrent protective devices. These devices are primarily designed to protect against excessive current that can cause damage to the electrical system, which typically includes both overload and short-circuit conditions.

However, overload protection is not guaranteed in all circumstances. Overcurrent devices operate based on predetermined settings, and many types of overcurrent devices may not respond quickly enough to protect against overloads under certain conditions. While some advanced settings and specific configurations, such as those found in motor starters or relay systems, can be designed to provide overload protection, many basic overcurrent devices function predominantly to interrupt current flow during short-circuit conditions rather than reliably addressing overload situations.

Therefore, while there are scenarios where an overcurrent device might be set up to provide overload protection, it is not a definitive characteristic for all such devices.
