SUBJECT: Technical Specifications for VariSTAR® MUS
Technical Data
TD-245MOV Arrester Modules – IEEE® Station/IEC Class 2
APPLICATION
These epoxy-fiberglass reinforced modules containing Metal Oxide Varistors (MOV) are for use
as active elements in IEC Class 2 and IEEE® station class gapless surge arresters when applied
in appropriately designed housing.
Individual modules are sealed within a plastic bag and display the module number, see Figure 3
and Figure 4.
