Overvoltage trigger, 230VAC 50Hz A-PKZ0(230V50HZ)-PI 199339

Overload trigger – precise protection and quick installation

This overload trigger, with a rated voltage of 230VAC 50Hz, is a key element ensuring reliable protection of motor starters. Its task is to react to sudden current increases, protecting the installation from damage and downtime. The device is particularly useful in applications where impulse loads occur, such as starting motors.

Design and application

The A-PKZ0(230V50HZ)-PI trigger is designed to work with Eaton motor starters, providing them with additional functionality in the field of short-circuit protection. Thanks to this solution, the installation is protected against the effects of short circuits and overloads, which translates into a longer lifespan of devices and minimizing the risk of failure. The initial and final value of the setting range of the instantaneous short-circuit release is 0A – which means that the device reacts immediately to exceeding the short-circuit threshold.

Advantages for the installer and user

• Quick installation: the use of spring clamps shortens the wiring time by up to 50% compared to traditional screw clamps. This translates into real time savings on site.
• High reliability: constant spring pressure in the clamps ensures resistance to vibrations and shocks, guaranteeing a stable electrical connection for a long time.
• Compatibility: the trigger is compatible with existing Eaton products and accessories with screw clamps, which facilitates modernization and expansion of the installation.
• Power consumption: low power consumption (0.5 W) minimizes energy losses and affects the energy efficiency of the system.
• Safety: provides effective protection against short circuits and overloads, protecting devices and electrical infrastructure.
• Versatility: dedicated to motor starters, but can also be used in other applications requiring a quick response to current increases.
