ABB ZM-16-PKZ2 Motor Protection Trip Module

Product Overview

The ZM-16-PKZ2 is a motor protection trip module from the Eaton Moeller PKZ2 product range. It provides adjustable overload and short-circuit protection for three-phase motors. When the motor current exceeds the configured limits, the module trips the associated motor protection switch to help prevent equipment damage.

Brand verification: Manufacturer documentation identifies this model as Eaton Moeller, rather than ABB. The product is also listed as discontinued in the manufacturer's documentation, so availability should be confirmed.

Protection Functions

Overload and short-circuit protection

Main Features

  • Adjustable Protection: Allows overload and magnetic trip settings to match motor requirements.

  • Motor Safety: Helps protect motors against excessive current and short circuits.

  • Phase Failure Sensitivity: Supports protection against single-phasing conditions.

  • Temperature Compensation: Helps maintain consistent protection under varying ambient temperatures.

  • Secure Settings: Protective covers help prevent unintended adjustment.

Typical Applications

This trip module is suitable for motor protection systems used in industrial machinery, conveyor equipment, pumps, compressors, and factory automation installations. It works with compatible PKZ2 equipment rather than functioning as a standalone motor starter.

Installation and Maintenance

Install the module only with a compatible PKZ2 base unit and follow the manufacturer's wiring and installation instructions. Set the overload current according to the motor nameplate and applicable protection requirements. Before maintenance, isolate the power supply and inspect the module and associated connections for signs of damage.
