FAQ

What is the function of the 'Test' button on the ZM-16-PKZ2?

The 'Test' button allows for a mechanical simulation of a trip event. Pressing it verifies the functionality of the tripping mechanism of the combined unit (trip block and base circuit-breaker) without requiring an actual overcurrent condition.

No, this trip block is specifically designed for the older, obsolete PKZ2 series. It is not mechanically or electrically compatible with the modern PKZM0 series from Eaton.

This range allows you to set the trip current to match the Full Load Amperage (FLA) of your specific motor. The dial should be set to the motor's nameplate FLA to ensure it trips correctly during an overload condition, thus protecting the motor windings from overheating.
