An assembly is an enclosure, such as a metal box, that holds a group of devices that together perform a complete function. These devices have to work together to ensure that the function occurs both properly as expected as well as safely. The devices are the various elements that are known as switchgear and controlgear. Assemblies include such elements as circuit breakers to protect against a short, contactors for remote control and overload relays to protect from overheating and burning.
