Weidmüller VARITECTOR PU AC IoT surge arrester devices

The VARITECTOR PU AC IoT surge protection devices were specifically developed by Weidmüller for stable 230/400 V networks, and are designed to provide top-level protection for industrial energy networks. The product features a real-time status monitoring function, which allows for live monitoring of the arrester. This function is useful when there are deviations from the standard, which are then automatically displayed to the user.

The VARITECTOR PU AC IoT records surge pulses and monitors the status of the protective conductor connection or the history of the temporary surge voltages. This makes it possible to draw conclusions on the service life of the arrester and to plan service work efficiently. In this case, the user will receive operating data to review, for example, or will be shown a message explaining that the arrester has come to the end of its service life and needs to be replaced at the next maintenance interval.

The IoT function can withstand the lightning current, meaning that the data for real-time monitoring is available even following a surge voltage. The intuitive integration into the Industrial IoT can also be carried out via web server. Using the MQTT protocol provides the user with the data in the form of standardised protocols that can be easily integrated into the user’s existing engineering systems.
