What would section Z in a typical magnetic starter signify?

In a typical magnetic starter, section Z is commonly used to denote a set of auxiliary contacts. Auxiliary contacts are important components that serve the function of providing additional control and signaling capabilities within the starter circuit. They can be normally open or normally closed, and they are utilized to provide feedback to control systems or indicate the operational status of the starter.

For example, when the magnetic starter is energized, the main contacts close, allowing power to flow to the motor, while the auxiliary contacts can be used to signal other devices or systems that the starter is engaged or to create interlocks for safety purposes. This function enhances the overall control strategy in electrical systems, allowing for greater flexibility and safety in operations.

The other sections mentioned represent different functions: the contactor section is where the main power contacts reside, the overload section contains the protection devices against motor overloads, and the control relay handles specific control logic but is not typically labeled as section Z.
