FBMOV Varistor Series  
Description  
The Littelfuse FBMOV Series thermally protected and  
non-fragmenting varistor represents a new development  
in circuit protection. It consists of a 40kA varistor building  
block (MOV) with an integral thermally activated element  
designed to open in the event of overheating due to  
abnormal over-voltage, limited current conditions.  
FBMOV series devices also include a varistor series fuse  
which prevents the part from rupturing when subjected to  
high fault current (up to 200kA).The tubular fuse-like body  
allows for easy mechanical connection in the application.  
Another feature of FBMOV is an indicator lead, which may  
be connected to monitoring circuitry and used to signal if  
the MOV has been disconnected.

FBMOV series devices offer quick thermal response due  
to the close proximity of the integrated fusing thermal  
element to the MOV body. The integrated configuration  
also offers lower inductance than most discreet solutions  
resulting in improved clamping performance to fast over-  
voltage transients.
