1. What is the primary function of this Type 2 SPD?
This Type 2 (T2) Surge Protective Device is designed to protect low-voltage electrical installations against surge voltages caused by indirect lightning strikes and switching operations.
2. Why does this device have 4 poles?
The 4P configuration provides complete protection for three-phase plus neutral (3P+N) systems, ensuring that all conductors, including the neutral line, are protected against voltage spikes.
3. How do I interpret the visual status indicator?
The multi-color indicator provides a quick visual check: typically, green signifies the device is operational, while a change in color (often red) indicates the internal thermal protection has tripped and the module needs replacement.
4. Can this SPD be monitored remotely?
Yes, this model includes remote signaling capability, allowing for connection to an alarm system or BMS to monitor the protection status from a central location.
5. Is it mandatory to use a professional for installation?
Yes, installation must be performed by qualified electrical personnel to ensure compliance with IEC 60364 standards and to guarantee the safety and effectiveness of the lightning protection system.
6. What happens at the end of its service life?
The device features thermal disconnectors. When it reaches the end of its life due to repeated surge handling, it safely disconnects from the grid and triggers the visual/remote status indicators.
