Basic circuit diagram DG M WE ... FM
Three-pole modular surge arrester for use in wind turbines with a rated varistor voltage U mov = 750 V
a.c.; FM version with floating remote signalling contact
• Prewired complete unit consisting of a
base part and plug-in protection modules
• High discharge capacity due to heavyduty
zinc oxide varistors/spark gaps
• High reliability due to "Thermo Dynamic
Control" SPD monitoring device
