ZOTUP IN PILLS | WHEN AND WHY CHOOSE AN SPD WITH/WITHOUT REMOTE SIGNALING CONTACT?

[12]

The Dilemma of Remote Signaling Contact

When we decide to protect our system with a surge protective device (SPD), we are often faced with an important choice: whether to opt for an SPD with or without remote signaling contact. Let's see why this decision is crucial.

Remote Signaling Contact: What Is It and How Does It Work

The remote signaling contact, or remote signaling, is an accessory that allows remote monitoring of the life status of the surge arrester. This is done through a clean contact exchange, which transmits a signal using a transmitter and a receiver.

Constant Remote Monitoring

If our system is located in a remote area, difficult to reach, or particularly exposed to lightning, the presence of remote signaling contact allows us to constantly monitor the situation without the need to visit the site in person.

Alert Signal: Prompt Intervention

ZOTUP surge arresters are equipped with a three-color progressive performance indicator. When the window turns completely yellow, the alert signal is immediately sent to the control center. This allows for prompt intervention and preventive replacement of the SPD before it becomes inactive.
