Which of the following is not a part of a fusible disconnect?

A fusible disconnect is an important component in motor control and electrical systems, serving to isolate electrical circuits for maintenance or safety purposes while also providing overcurrent protection through a fuse. The key components of a fusible disconnect typically include a fusible link or fuse for overcurrent protection, a cutout switch that allows for the disconnection of the circuit, and a disconnect handle that enables users to safely operate the disconnect mechanism.

In this context, it’s important to understand that a fusible link is the element that houses the fuse, providing the crucial functionality for circuit protection. The cutout switch allows an operator to completely disconnect the circuit from the power source, aiding in safe operation and maintenance procedures. The disconnect handle enables physical operation of the disconnect mechanism by the user.

Given that all three components—fusible link, cutout switch, and disconnect handle—are integral parts of a fusible disconnect, the statement that none of the parts listed are excluded from the fusible disconnect is correct. As each option represents a legitimate component of a fusible disconnect system, it reinforces the principle of the device's design and operation.
