Frequently Asked Questions
What is the main function of the GSP9-12.5 Surge Protection Device (SPD)?
The GSP9-12.5 is designed to protect electrical installations and terminal equipment against transient overvoltages caused by lightning strikes or industrial switching operations.
What does the "prewired complete unit" structure benefit?
It consists of a preassembled base part and plug-in protection modules. This modular design makes installation much simpler and allows for faster module replacement without rewiring the entire unit.
How does the "temperature-controlled" SPD monitoring device work?
The integrated temperature control device constantly monitors the thermal state of the varistors. It automatically disconnects the protection module from the network in case of overheating or overload, ensuring high operational reliability.
What are zinc oxide varistors and GDT used for in this device?
Heavy-duty zinc oxide varistors and Gas Discharge Tubes (GDT) provide a high surge current discharge capacity, rapid response times, and reliable voltage protection levels for your circuits.
Is this SPD suitable for single-phase systems?
Yes, the 1P+N configuration is specifically designed for single-phase power systems (Phase + Neutral) to protect connected equipment from line-to-line and line-to-earth surges.
