Project Description
FLP7-440/4S
Description
Modular surge arrester for use in TN-S systems with floating remote signaling contact.
- Prewired complete unit consisting of a base part and plug-in protection modules
- High discharge capacity due to heavy duty zinc oxide varistors/spark gaps
- High reliability due to “Thermo Dynamic Control” SPD monitoring device
