Function of the fuse
Essential to interrupt the mains lead after spark over of the surge protector.
Î Only use slow-blow fuses with ”high breaking capacity”. Depending on the fuse
in the mains lead, use fuses between 6 A and 10 A.
Surge protector cartridges (UCV...)
The plug-in surge protector cartridges model UCV... consist of an inert gas-filled,
high-performance surge protector with zinc oxide varistor connected in parallel.
Inspection and replacement:
– Make a visual check when servicing the control unit. Preventive replacement of
the UCV is not necessary
– brown or black discoloration of the porcelain body = defective UCV
